Study Notes
Selecting Breeding Animals
- Consider the animal's family history (pedigree) to identify potential carriers of diseases
- Physical assessments are crucial to evaluate physiological health and potential breed-specific health issues
- Behavioural assessments are necessary to determine temperament and tractability (ease of handling)
- Evaluate the animal's living arrangements and ensure suitable housing is available
- Consider the compatibility of different breeds, for example, Chihuahua and Great Dane, to avoid potential conflicts or health issues
Breeding Ethics
- Breeding can be expensive, tiring, and time-consuming
- Breeding carries high risks
- Breeding can be rewarding, but it can also be easily abused
Concerns and Motivations
- The lack of policing in some countries (e.g., the US) and even in local breeding at home (puppy mills) raises concerns about animal welfare
- Questionable motivations behind breeding, such as: • Financial gain (money) • Employment (job) • Working dogs • Fancy pets (e.g., fancy cat) • Unusual or exotic pets (e.g., super clever flying rabbit)
Natural Selection and Survival
- The environment selects certain traits in animals, leading to the survival of the fittest.
- Charles Darwin's concept of natural selection states that the better adapted an individual is to its environment, the more likely it is to survive.
Desired Traits in Breeding
- Traits that ensure survival and easy care, such as:
- High libido
- Easy birthing and good mothering
- Short haired varieties
- Avoidance of genetic diseases
- Traits that increase suitability for intended use, such as:
- High trainability for competition or work
- Low aggression for family pets
- Traits that meet breed standards, such as:
- "Good looks" for showing
Undesired Traits in Breeding
- Traits that are socially unacceptable, such as:
- Breeding aggressive bitches and producing aggressive pups
- Bitches no longer vomiting food for their pups

Artificial Selection in Animals
- Humans have selectively bred animals for centuries to acquire desirable traits.
- Desirable traits in animals include:
- Easy care and survival
- Increased trainability
- More production (e.g., milk, eggs, meat)
- Reduced fear and aggression
- Socially acceptable characteristics
Desirable Traits in Dogs
- In dogs, humans have selected for traits such as:
- High libido and easy birthing
- Good mothering abilities
- Short-haired varieties for low maintenance
- Avoidance of genetic diseases
- Suitability for intended use (e.g., herding, guarding)
Breeding Goals for Working Dogs
- In working dogs, breeder goals include:
- High trainability for competition or work
- Low aggression for safe family pets
- Conformance to breed standards for showing
Negative Consequences of Artificial Selection
- Artificial selection has gone wrong in cases where:
- Breeders prioritize 'good looks' over health and well-being
- Breeding aggressive bitches can produce aggressive pups
- Unnatural selection can lead to negative traits (e.g., bitches no longer vomiting food for their pups)

Line-Breeding Issues
- To breed a purebred dog, a closed gene pool is required, which can lead to a narrow gene pool.
- Breeders often prefer to breed from 'champion' dogs, contributing to the 'popular sire syndrome'.
- When a popular breeding dog carries faulty or disease-causing genes (mutations), these genes are spread within the offspring.
- If both parents carry the same faulty gene, it can be expressed in the offspring.
- Lack of genetic diversity in breeds increases the likelihood of offspring having heritable disorders.
- Healthy species have genetic diversity, which decreases the likelihood of offspring with heritable disorders.
