If BW is between 2 and 45 kg, RER (kcal) is approximately 30 * ( BW [kg])^0.75
MER depends on physiological state and ranges from 1.0 * RER in lower activity dogs to 3.0 * RER in highly active dogs

Nutrition Unique to Cats

Cats are obligate carnivores; dogs are omnivores
Cats have lower liver glucokinase activity compared to dogs, making them less able to metabolize simple carbohydrates
Their body requires a higher percentage of animal-based protein than dogs
Cats have a higher requirement for arginine compared to dogs

Nutritional Considerations in Dogs

Dog food should be formulated for specific life stages (e.g., puppy, adult, senior) and breed size
It is essential to choose a diet formulated for the specific needs of your dog and their lifestyle, including activity level and health status
It is recommended to select foods that have passed AAFCO (Association of American Feed Control Officials) feeding trials to ensure they meet nutritional standards
The "guaranteed analysis" on dog food labels should be reviewed to ensure it provides adequate information on the minimum percentages for protein and fat and the maximum percentages for crude fiber and moisture.

Feeding Guidelines for Dogs

Commercial diets are typically balanced and provide a variety of essential nutrients. These diets should be selected based on the dog's age, breed, and activity level.
Homemade diets require careful planning and supplementation to ensure balanced nutrients.
Dogs requiring special dietary needs (e.g., allergies, weight management) may need specially formulated diets.

Nutritional Considerations for Cats

Strict carnivore diet requirement: Cats need a high percentage of animal-based protein in their diet
Essential nutrients: Cats require taurine, arachidonic acid, and Vitamin A from their diet
Avoid high levels of simple carbohydrates and excessive amounts of plant-based protein sources
Choose foods with meat as the first ingredient
Cats have a higher fat requirement than dogs and should be fed a diet that meets this need.
Avoid feeding cats food designed for dogs, as it can lead to deficiencies
Dry food offers lower calorie density per volume than wet food. Some cats may struggle to meet their energy needs solely on dry food.
Wet foods are typically higher in moisture content and can be helpful for cats prone to urinary tract issues.

Feeding Guidelines for Cats

Cats prefer to eat multiple small meals throughout the day
Allow for free feeding, but monitoring food intake is important
Indoor cats require less caloric intake compared to outdoor cats, but appropriate food selection is still crucial for health.

Nutrition During Pregnancy and Lactation in Dogs

Increase calorie intake in late stages of pregnancy and during lactation, with a focus on energy density.
Enhance protein levels for fetal and puppy growth during pregnancy, with further increases during lactation.
Adequate hydration is crucial, especially during lactation.

Nutritional Considerations in Specific Conditions

Conditions like obesity, diabetes, and kidney disease require specific dietary adjustments.
Consultation with a veterinarian is essential for proper dietary management.

Nutrient Supplementation

Supplements should be considered only after consulting with a veterinarian.
Supplements should be used to fill nutritional gaps or address specific needs but not to replace a balanced diet.

Homemade Diets

Homemade diets require careful planning and supplementation to ensure balanced nutrients.
Consultation with a veterinarian is essential to ensure the diet meets all the animal's requirements.

Portosystemic Shunt

Protein should be from a highly digestible source
Protein content may need to be moderately restricted if signs of hepatic encephalopathy are present
Fat is an important source of calories

Chronic Hepatitis or Cirrhosis

Hypoalbuminemia is a concern with hepatitis, and protein intake should be maintained at normal adult levels
If signs of hepatic encephalopathy are present, protein should be restricted
Adequate caloric intake is important to prevent tissue catabolism

Dietary Changes

Gradual transitions between diets are recommended to allow the animal's digestive system to adapt.
Introduce new foods slowly over a period of days or weeks to minimize gastrointestinal upset.

Feeding Strategies

Multiple smaller meals per day are beneficial for many animals, particularly those with a higher metabolism or digestive issues.
Feeding schedules can be adjusted based on the animal's individual needs and preferences.

Water

Water is the most important nutrient
The daily water requirement is roughly 1.6 times the resting energy requirement (RER) for dogs and 1.2 times the RER for cats

Carbohydrates

Include sugars and starches
Utilized as a source of glucose
Carbohydrate ingredients include grains such as wheat, corn, rice, barley, and oats
Cooking increases the digestibility of carbohydrates

Fiber

Resist enzymatic digestion; is fermented in the colon.
Promotes and regulates normal bowel function
Fiber sources differ in their fermentation properties
The amount of fiber in the diet impacts bowel function

Calorie content

The kcal/g of diet (metabolizable energy [ME]) is typically not provided on the pet food label
ME can be obtained either from product literature or directly from the manufacturer
Two diets can be quite different in terms of ME even if they appear similar in percentages of protein and fat
Diets should not be compared on the basis of percentages, but they should be compared using ME

Calcium

Deficiency: Decreased bone mineralization, bone fractures
Excess: Nephrosis, enlarged costochondral junctions

Phosphorus

Deficiency: Pica, rickets, poor growth
Excess: Bone loss, calcification of soft tissues

Potassium

Deficiency: Anorexia, heart and kidney lesions
Excess is rare

Sodium and Chloride

Deficiency: Inability to maintain water balance
Excess: Thirst. Seizures, death

Magnesium

Deficiency: Muscular weakness, irritability, decreased bone density, seizures
Excess: Uroliths, paralysis

Protein

Cats have a much higher protein requirement than dogs due to the high activity rate of liver transaminases and deaminases.
Dogs (omnivores) and herbivores can decrease this enzyme activity when low-protein diets are fed, but cats cannot.
Arginine is required in cats for the conversion of ammonia to urea. Arginine-deficient diets rapidly result in ammonia toxicity.
Taurine is required in cats due to their low rate of taurine synthesis. Unlike other species, cats can only utilize taurine for conjugation with bile acids.
Deficiency of taurine leads to central retinal degeneration, reproductive failure, and the development of dilated cardiomyopathy.
Taurine is abundant in animal tissues but absent in plants.
Methionine and cystine are sulfur-containing amino acids required in high levels by cats.

Feline Nutrition

Restrict dietary protein to one or two protein sources
Avoid excess levels of dietary protein
Protein should be highly digestible
Avoid foods that contain wheat, barley, or rye in dogs with diarrhea.
Avoid foods that contain tuna or mackerel.
Feed a food that has reduced or no food additives.

Congestive Heart Failure

Avoid excess sodium intake
Prescription diets formulated for cardiac disease have the lowest concentration of sodium
Many geriatric foods and renal diets also contain lower amounts of sodium compared with regular adult diets.
Electrolyte abnormalities may occur as a result of the administration of cardiac drugs
- Diuretics may cause a loss of potassium and magnesium
- Angiotensin-converting enzyme inhibitors may cause hyperkalemia
Restrict phosphorus if chronic renal failure is present
Feed a moderate fat level
Feed a diet that is highly digestible
Either feed a diet low in fiber, or feed moderate mixture of soluble and insoluble fiber
Glutamine supplementation is beneficial.

Inflammatory Bowel Disease (IBD)

Limit dietary protein to one or two sources
The diet should be a highly digestible protein source.
Hypokalemia and dehydration are common, so make sure there is adequate water and potassium consumption
Feed a moderate fat content. High-fat foods contribute to diarrhea.
Fiber should be fed at a moderate level.
Fiber sources such as beet pulp, fructo-oligosaccharides or inulin produce volatile fatty acids that may be beneficial
Zinc deficiency can occur in IBD, so assess zinc consumption
Omega-3 fatty acid supplementation may be beneficial
Feed multiple small meals per day

Antioxidant Vitamins

Antioxidant vitamins such as vitamins E and C may have benefit to prevent lipid peroxidation

Feline Hepatic Lipidosis

Provision of adequate calories is most important
Many cats are fed via feeding tube
Protein deficiency may play a role in the pathogenesis of hepatic lipidosis. Moderate amounts of protein should be fed and should contain adequate taurine and arginine
Potassium supplementation should be considered because many cats with hepatic lipidosis are hypokalemic
Feed a diet with an increased level of insoluble fiber

Pancreatic Disorders

Exocrine pancreatic insufﬁciency
- Feed a highly digestible food with added pancreatic enzymes
- The diet should be very low in fiber
- Fat content should be low to moderate. MCT oil may be added if additional calories are needed
- Fat-soluble vitamin supplementation should be considered
Pancreatitis
- Discontinue oral intake of food and water until vomiting stops. Provide parenteral nutrition if necessary.
- Avoid excess dietary protein because free amino acids can stimulate pancreatic secretion. Maintain adequate protein ingestion
- Ensure adequate water intake
- Feed a diet low to moderate in fat
- Limit dietary protein to one or two sources.

Cancer

Cancer cachexia is an important issue.
Chemotherapy and radiation therapy may impact the ability to consume food.
Nutritional support is important.

Mineral Deficiency & Excess

A variety of medical problems can result from deficiency or excess of minerals.
Minerals from animal sources are more readily utilized than minerals from plant sources.

Vitamins

Vitamins A, D, E, and K are fat-soluble vitamins.
Intestinal absorption requires bile salts and micelle formation; absorption is by passive transport.
They are stored in fat; thus deficiency is less likely; however, they are more likely to cause toxicity.
The remaining vitamins are water soluble and are absorbed by active transport.
They can be depleted, rapidly causing deficiency; toxicity is uncommon.

Vitamin A

Deficiency: Anorexia, poor growth, weakness, fetal resorption
Excess: Tooth loss, poor growth, cervical spondylosis

Vitamin D

Deficiency: Rickets, osteomalacia, bone fractures, enlarged costochondral junctions
Excess: Hypercalcemia, calcinosis, anorexia, lameness

Vitamin E

Small batches of food should be made because these diets do not contain preservatives.
Food should be kept in the refrigerator between feedings, and larger batches can be frozen.

Guaranteed Analysis Panel

Must include the minimum percentages for protein and fat and maximum percentages for crude fiber and moisture.
Percentages are "as-fed" and do not give any indication as to the caloric density or digestibility of the product.

Nutritional Adequacy Statement

Tells whether the product is designed for adult maintenance or growth and reproduction.
There are two methods for determining nutritional adequacy: formulation method and feeding trial method.

Nutritional Considerations for Dogs

Avoid excess dietary sodium.
Ensure adequate caloric intake.
If hypokalemia occurs, provide potassium supplementation (especially in cats).
-3 fatty acid supplementation may be beneficial.
Calcitriol levels decrease in renal failure and may need to be supplemented to prevent secondary hyperparathyroidism.

Nutritional Considerations for Homemade Diets

Patients consuming homemade diets should be evaluated by a veterinarian at least 2 to 3 times per year.
Special attention should be paid to the skin and hair.
Calcium and vitamin D status should be monitored, as nutritional secondary hyperparathyroidism is not uncommon in animals receiving a diet deficient in calcium or vitamin D or excessive in phosphorus.

Nutritional Considerations for Cats

Cats are strict carnivores; dogs are omnivores.
Cats have a low liver glucokinase activity and thus cannot metabolize a large amount of simple carbohydrate.

Protein Metabolism in Cats

Restrict dietary phosphorus.
Avoid excess levels of dietary protein. Protein should be highly digestible.

Dietary Considerations for Dogs with Diarrhea

Avoid foods containing wheat, barley, or rye.
Avoid foods that contain tuna or mackerel.
Feed a food that has reduced or no food additives.

Nutritional Considerations for Dogs with Congestive Heart Failure

Avoid excess sodium intake.
Prescription diets formulated for cardiac disease have the lowest concentration of sodium.
Many geriatric foods and renal diets also contain lower amounts of sodium compared with regular adult diets.

Electrolyte Considerations for Dogs with Congestive Heart Failure

Electrolyte abnormalities may occur as a result of the administration of cardiac drugs.
Diuretics may cause a loss of potassium and magnesium.
Angiotensin-converting enzyme inhibitors may cause hyperkalemia.
Restrict phosphorus if chronic renal failure is present.

Nutritional Considerations for Dogs with Hepatic Disease

Maintain adult protein requirements unless there are signs of hepatic encephalopathy.
Restrict copper intake. Diets should not contain more than 5 ppm copper on a dry matter basis.
Zinc supplementation can be used partially to block copper absorption.
Antioxidant vitamins such as vitamin E and vitamin C may be beneficial to prevent lipid peroxidation that occurs in copper-associated hepatotoxicosis.

Nutritional Considerations for Dogs with Portosystemic Shunt

Protein should be from a highly digestible source.
Protein content may need to be moderately restricted if signs of hepatic encephalopathy are present.
Fat is an important source of calories in animals with portosystemic shunt.

Nutritional Considerations for Dogs with Chronic Hepatitis or Cirrhosis

Hypoalbuminemia is an important problem with hepatitis, and protein intake should be maintained at normal adult levels.
Fat should be moderate and easily digestible.
Feed a moderate mixture of soluble and insoluble fiber.

Nutritional Considerations for Dogs with Inflammatory Bowel Disease (IBD)

Limit dietary protein to one or two sources.
The diet should be a highly digestible protein source.
Hypokalemia and dehydration are common, so make sure there is adequate water and potassium consumption.
Feed a moderate fat content. High-fat foods contribute to diarrhea.
Fiber should be fed at a moderate level.
Fiber sources such as beet pulp, fructo-oligosaccharides or inulin produce volatile fatty acids that may be beneficial.
Zinc deficiency can occur in IBD, so assess zinc consumption.
Omega-3 fatty acid supplementation may have benefit.
Feed multiple small meals per day.

Nutritional Considerations for Dogs with Pancreatic Disorders

Feed a highly digestible food with added pancreatic enzymes for dogs with exocrine pancreatic insufficiency.
The diet should be very low in fiber.
Fat content should be low to moderate. MCT oil may be added if additional calories are needed.
Fat-soluble vitamin supplementation should be considered.
Discontinue oral intake of food and water until vomiting stops. Provide parenteral nutrition if necessary.
Avoid excess dietary protein for dogs with pancreatitis. Free amino acids can stimulate pancreatic secretion.
Maintain adequate protein ingestion.

Nutritional Considerations for Dogs with Cancer

Cancer cachexia is an important issue. Nutritional support is critical for dogs with cancer.
Chemotherapy and radiation therapy may impact the ability to consume food.

Nutritional Considerations for Cats with Hyperlipidemia

The addition of -3 fatty acids in the form of fish oil supplementation can be very effective at lowering triglyceride concentrations.

Nutritional Considerations for Cats with GI Disorders

A high dietary fat content can help maintain adequate calories. A lower fat content is a better option if there is esophageal reflux.
Dietary protein content should be greater than 25% dry matter.
A gruel consistency is best if there is esophageal obstruction or esophagitis. Dry food or a bolus of moist food is better if there is megaesophagus.
Feeding small amounts of food in an upright position is recommended.

Nutritional Considerations for Cats with Hairballs

Larger kibble size increases the passage of hairballs out of the stomach and decreases vomiting.
An increase in dietary fiber can help prevent hairballs.

Nutritional Considerations for Cats with Feline Lower Urinary Tract Disease (FLUTD)

Feed a diet with an increased level of insoluble fiber.

Nutritional Considerations for Cats with Feline Hepatic Lipidosis

Provision of adequate calories is most important.
Many cats are fed via feeding tube.
Protein deficiency may play a role in the pathogenesis of hepatic lipidosis. Moderate amounts of protein should be fed and should contain adequate taurine and arginine.
Potassium supplementation should be considered because many cats with hepatic lipidosis are hypokalemic.
Copper-associated hepatotoxicosis can occur.

Nutritional Considerations for Cats with Diabetes

Ensure adequate hydration.
Feed a diet with a moderate percentage of fat in the diet.
It's important to manage weight in diabetic cats as this will improve insulin sensitivity.

Energy Requirements: Dogs

Resting Energy Requirement (RER): RER (kcal) = 70 * (body weight [BW] [kg]) ^ 0.75
Maintenance Energy Requirement (MER): Ranges from 1.0 * RER in obese individuals to 1.8 * RER in intact adults
Work Energy Requirement: Ranges from 2 * RER for light work to 8 * RER for heavy work
Gestation: First 42 days, feed as an intact adult (1.8 * RER). Last 21 days, feed 3 * RER (or more if needed)
Lactation: Energy requirement ranges from 4 to 8 * RER, depending on the number of puppies nursing
Growth: First 4 months of life, about 3 * RER. After 4 months, about 2 * RER until adult size is reached

Energy Requirements: Cats

RER: Calculated as for dogs
MER: Ranges from 0.8 * RER in obese individuals to 1.6 * RER in active intact adults
Gestation: Energy requirements increase linearly during gestation. Feed at 1.6 * RER at breeding and gradually increase to 2 * RER by parturition. Free-choice feeding is recommended
Lactation: Energy requirement ranges from 2 to 6 * RER, depending on the number of kittens

Pet Food Labels

Display Panel: Must include the manufacturer’s name, the name of the product, net weight, which stage of life the food is designed for, a description of the product, and the nutrition claim

Homemade Diets

Recipes should be chosen from reputable sources or formulated by a veterinary nutritionist
All foods should be cooked to destroy bacteria
Recipes need to be strictly followed with minimal substitution to ensure nutritional adequacy
A gram scale for weighing ingredients is recommended
Periodically, a sample of the diet should be submitted to a laboratory for analysis to ensure nutritional content

Special Considerations for Cats

High levels of animal protein (approximately 20%) are required for cats due to unique nutritional requirements
Arachidonic acid is required in the diet as cats cannot synthesize it from linoleic acid
Niacin is required in higher amounts than dogs because cats do not have sufficient conversion of tryptophan to niacin
Pyridoxine is required in higher quantity than dogs because of the high transaminase activity
Cats cannot convert vitamin A precursors to vitamin A, as can dogs

Urolithiasis (Canine)

Calcium oxalate uroliths (prevention):
- Encourage water intake
- Avoid excess dietary protein
- Avoid excess dietary calcium and sodium
- Avoid both an excess or deficiency of magnesium
- Low levels of iron may be beneficial to slow tumor growth
