Canine History & Evolution Quiz

Canine History & Evolution

• Domestic dogs, Canis lupus familiaris, are derived from the gray wolf, part of the Canidae family.
• Dogs were likely the first domesticated animals, serving as hunting, working, and companion animals throughout history.
• Approximately 900 million dogs exist globally, with 75% being free-range.

Domestication

• Dogs were domesticated from gray wolves around 15,000 years ago, rapidly becoming integral to human society.
• Their roles include hunting, herding, protection, and as support for people with disabilities.
• The selective breeding process has resulted in hundreds of distinctive breeds, displaying more variation than any other land mammal.
• Height Range: From a few inches in Chihuahuas to several feet in Irish Wolfhounds.
• Color Variations: Spanning from white and gray to black and a variety of browns.
• Coats: Can be short or long, with various textures including coarse or smooth.

Differences Between Dogs and Wolves

Physical Comparisons

• Domestic dogs have smaller skulls (20% smaller), smaller brains (30% smaller), and smaller teeth than wolves.
• Dogs need fewer calories and have thicker skin compared to wolves.

Behavioural Comparisons

• Dogs excel in operant conditioning but are less capable of observational learning compared to wolves.
• Feral dogs lack complex social structures and do not impose feeding hierarchies typical in wolves.
• Male dogs typically do not take part in raising their young or displaying aggression towards others' young.

Evolution and Human-Dog Relationship

• Wolves and their dog descendants gained advantages from living in human camps, such as safer environments and reliable food sources.
• The companionship of dogs improved sanitation and provided warmth for early human communities.
• Dogs significantly assisted in hunting, helping increase human survival rates and success.

Dmitry Belyaev’s Research

• Belyaev's experiment with domesticated silver foxes selected for tameness resulted in notable behavioural and morphological changes.
• Domesticated foxes showed lower adrenaline levels, leading to tameness and physical changes like spotted fur.
• Selective breeding for tameness in foxes offers insights into dog domestication, emphasizing behaviour over size or reproduction.

Canine Development Stages in Relation to Training

Neo Natal Period (Birth to 12 days)

• Puppies are completely dependent, lacking senses, unable to regulate temperature, and show reflex reactions only.

Transition Sub Period (13-21 days)

• Puppies start to respond to light and movement, becoming more mobile and beginning to interact with their environment.

Awareness Period (21-23 days)

• Rapid sensory development; puppies recognize humans and begin social bonding, requiring stable environments.

Canine Socialization Period

• Primary Socialization (3-5 weeks): Puppies learn through intense play fighting and develop fundamental dog behaviours.
• Secondary Socialization (6-12 weeks): External interactions expand, providing optimal learning opportunities and developing social skills.

Human Socialization Period (7-12 weeks)

• Puppies are highly receptive to learning. Early training enhances mental development and the ability to socialize with new environments and people.

Fear Imprint Period (8-11 weeks)

• Traumatic experiences may cause long-lasting effects, necessitating careful management of interactions during this sensitive period.

Seniority Classification Period (10-16 weeks)

• Puppies clarify rank in social settings and experience rapid growth; consistent leadership is critical.

Flight Instinct Period (4-8 months)

• Changing behaviours may lead to temporary forgetfulness of previous training; socialization and training must be prioritized before this stage.

Second Fear Period (6-14 months)

• This period may lead to increased reactivity and protection behaviors as puppies mature. Patience and positive reinforcement are crucial for navigational challenges.

Health Considerations

• Limit training sessions to short durations and avoid over-exercising puppies to prevent health issues.

Maturity Stage (1-4 years)

• Refers primarily to sexual maturity; continued socialization and training efforts are vital to fostering well-adjusted adult dogs.### Under Socialized Dogs
• Poor socialization during puppyhood can lead to lifelong behavioral and cognitive deficits.
• Isolated puppies struggle with social contact and often become extremely fearful of interaction.
• Lifelong consequences of isolation include learning difficulties, hyperactivity, emotional instability, and inability to handle novel situations.
• Social and sexual incapacitation can result from lack of early social exposure.

Dog Breed Groups and Common Training Challenges

• Hounds, bred for hunting and tracking, are independent and often work solo.
• They can be distracted easily by movement and scents, making training challenging.
• Hound types include Sighthounds, which hunt by sight, and Scenthounds, which track using their sense of smell.
• Hounds vary significantly in size, from the small Dachshund to the large Irish Wolfhound.
• Exercise requirements differ among hounds; some need minimal exercise, while others require extensive space to run.

Common Training Challenges

• Scent Hounds prioritize scent investigation, making focus on commands more difficult.
• Using high-value smelly treats can improve focus during training.
• Incorporating scent games can help redirect a Scent Hound's attention and utilize their natural tracking abilities effectively.
