Study Notes

Parasites

Worms

Roundworms (Ascarids): Common in dogs, especially puppies; contracted from the mother. Symptoms include an enlarged belly, poor weight gain, vomiting, diarrhea, and visible worms in feces.
Hookworms (Ancylostoma): Small bloodsucking worms found in warm, humid areas. Symptoms include black stool, pale gums, weight loss, and anemia.
Tapeworms: Acquired by ingesting infected fleas or rodents. They can grow up to several feet and require destruction of the head for treatment, as it can regenerate if not removed.
Whipworms: Contracted by consuming eggs from contaminated sources. Symptoms include diarrhea with urgency, weight loss, and anemia, with eggs remaining viable in soil for up to five years.
Heartworms: Transmitted by mosquitoes; more prevalent in outdoor dogs. Symptoms include coughing, difficulty breathing, and fainting.

Skin Parasites (Ticks, Fleas, Lice, Mange)

Ticks

Adult ticks measure between 0.4 cm to 1.4 cm and prefer feeding on dogs.
They can attach, feed, and drop off to lay eggs.
Prevention includes avoiding infested areas and daily body checks for ticks. Proper removal technique involves leveraging tweezers for extraction.

Fleas

Fleas, small brown insects, feed on blood, causing mild to severe reactions in dogs, particularly in small breeds.
Heavy infestations may lead to severe anemia.
Fleas serve as intermediate hosts for tapeworms and can be detected by fecal examination.

Mange

Demodectic Mange: Common in puppies; caused by mites in hair follicles. Localized patches of hair loss can heal naturally, while generalized cases need special treatment.
Sarcoptic Mange (Scabies): Contagious to humans, causing severe itching, inflammation, and ulcers. Requires veterinary oversight.
Cheyletiella Mange (Walking Dandruff): Highly contagious, affecting young puppies with red rashes and flaky skin requiring treatment of all exposed animals.

Lice

Wingless insects found primarily on neglected dogs; transmitted by direct contact. Causes intense itching and self-inflicted wounds.

Fungal Infection

Ringworm (Dermatophytosis): Affects hair and follicles; transmitted through spores and requires careful environmental cleaning. Diagnosis is done via fungal culture.

Nutrition

Critical for optimal health and directly impacts a dog’s skin, coat, energy levels, and gastrointestinal function.
Select high-quality, balanced diets appropriate for the dog's age, size, and lifestyle.

Types of Dog Food

Commercial Diets: Available in wet or dry form.
Generic or Economy Food: Low-cost, often made from inferior ingredients, with potential allergens.
Premium Foods: Offer better quality but may still contain questionable ingredients.
Natural Foods: Recommended by holistic professionals, free from artificial additives.

Feeding Practices

Meal feeding with monitored portion sizes is preferred for nutritional health.
Free-choice feeding may lead to food guarding and other issues, especially in multi-dog households.

Water

Ensure access to clean water as it is essential for various body functions.

Common Ailments

Ear Infections: More frequent in floppy-eared dogs; vigilance in ear cleaning is crucial.
Skin Allergies: Triggered by allergens; cause intense itching and various skin problems.
Pyoderma / Hot Spots: Skin infections that arise from trauma. Hot spots are painful, wet patches that require prompt attention.
Gastritis / Vomiting: Causes include irritants and overeating; persistent vomiting may indicate serious health issues.
Motion Sickness: Common in young dogs; can often be mitigated through management strategies like travel in a covered crate.

Side Effects of Improper Nutrition

Nutritional deficiencies can lead to allergies, obesity, and serious health issues, impacting longevity.
Obesity can strain internal organs and bones, with rising prevalence linked to sedentary lifestyles and palatable food options.
Malnourishment: Signs include a bloated abdomen and visible ribs.

Conclusion

Proper canine nutrition, parasite control, and awareness of common ailments are essential for maintaining canine health and well-being. Regular vet consultations and proactive health measures contribute significantly to a dog's quality of life.### Diarrhea
Common causes include dietary indiscretion and intestinal parasites; also associated with various infectious diseases.
Diarrhea classifications: acute (sudden onset, short duration) and chronic (gradual onset, persists for over three weeks, warrants veterinary attention).
Sudden changes in diet, food intolerance, drug side effects, and living circumstances can trigger diarrhea.

Enteritis

Gastrointestinal infection characterized by sudden vomiting and diarrhea, rapid pulse, fever, apathy, and depression.
May involve blood in vomit and diarrhea; rapid dehydration is a significant concern, particularly in dogs under one year or over ten years old.
Most common cause is parvovirus; other causes include garbage poisoning and ingestion of toxic substances.
Serious condition requiring veterinary attention if diarrhea and vomiting occur simultaneously.

Benign Skin Tumors

Common in dogs; differentiation between benign and malignant tumors is challenging.
Definitive diagnosis can only be made through biopsy.

Osteoarthritis

Progressive degenerative arthritis affecting joints; commonly occurs in dogs with inherited orthopedic diseases or joint injuries.
Affects one in five dogs during their lifetime, leading to lameness, stiffness, and joint pain.
Symptoms are more pronounced in the morning or after lying down; behavior changes may occur due to increased disability.
Treatment options include physical therapy and weight control to improve quality of life.

Hypothyroidism

Thyroid deficiency affecting metabolism; the thyroid produces thyroxine ($T_4$), regulating metabolic rates.
Affects less than one percent of dogs, mainly middle-aged medium to large breeds.
Permanent condition treatable with daily or bi-daily thyroid hormone replacement.

Bloat (Gastric Dilatation Volvulus - GDV)

Life-threatening condition primarily seen in larger dog breeds; potential link to commercial feeding practices, especially large concentrated meal portions.
Most common in dogs aged two to ten years, typically occurring at night.
High mortality rate (approximately 50%); early recognition and treatment are critical for survival.
Symptoms include abdominal enlargement, excessive drooling, restlessness, and unsuccessful vomiting attempts.

When to See a Vet

Immediate veterinary consultation is advised if the dog exhibits:
- Blue, white, or pale gums
- Labored breathing or collapse
- Dizziness, imbalance, or inability to walk
- Extremely bloated abdomen or seizures

Preventing Bloat

Feed three smaller meals per day rather than one large meal.
Restrict access to water for one hour before and after meals.
Prevent large amounts of water consumption at once.
Avoid strenuous exercise after meals.
Be vigilant about early signs and seek prompt veterinary care.
