## 8th Grade Science | Cocker Spaniel Mini Research Project
- **Student:** Buddy
- **Subject:** Selective breeding and breed profile of the Cocker Spaniel.

## Breed Profile
- **Size:** Medium (20–30 lbs), 14–15 inches tall.
- **Appearance:** Silky, wavy coat (golden, black, brown, or parti-color); long floppy ears and expressive eyes.
- **Personality:** Gentle, cheerful, playful, and loyal.

## Origin & History
- **Origin:** England and Spain; name derived from 'Spaniel' (Spain).
- **Timeline:** Developed between the 14th–19th centuries; recognized as a breed in 1892.
- **Original Purpose:** Bred as hunting dogs to flush and retrieve woodcock birds (hence the name 'Cocker').

## Genetics & Selective Breeding
- **Trait Selection:** Bred for floppy ears (scent funneling), compact bodies (brush navigation), and 'soft mouths' (retrieval without damage).
- **Evolution:** Over time, breeding shifted focus from pure hunting skill to a balance of skill and gentle temperament for companionship.

## Jobs & Roles
- **Modern Roles:** Family pets, therapy and service dogs, hunting companions, and scent detection (police/military).

## Health & Genetics
- **Trade-offs:** Selective breeding for specific physical traits led to health issues.
- **Ear Infections:** Long ears trap moisture and limit airflow.
- **Eye Problems:** Genetic tendency toward Progressive Retinal Atrophy (PRA) which can cause blindness.

## Interesting Facts
- **Famous Owners:** President Richard Nixon's dog 'Checkers'.
- **Pop Culture:** 'Lady' from Disney's *Lady and the Tramp* is an American Cocker Spaniel.
- **Senses:** Nose contains 220 million scent receptors (humans have 5 million).
- **Types:** Distinct English and American varieties exist.

## Conclusion
- Selective breeding is a purposeful process humans use to shape animal traits for specific needs, affecting both physical body and personality.
