(lecture) dog management Flashcards
4 theories of dog domestication:
1) Selection of wolf puppies
2) Wolves exploited food sources from human activity
3) Dogs and humans co-evolved
4) Diversification of dogs with cultural and technological changes
very complex and likely combo of many things
sight: (compare to humans - 3)
- 6x less sensitive to DETAIL than humans
- WIDER field of vision than human
- LESS binocular vision (= less 3D vision)
sight: main features (3)
- tapetum lucidum (layer of tissue which reflects light back to retina)
- stereoscopic (visual info from 2 eyes to create 3D image)
- cannot see red (red-green colour blind)
smell: olfactory epithelium area cover (NOT THICKNESS)
18-150CM2 (?)
(HUMAN 3CM2)
smell: olfactory receptors
220million
(human 5mil)
body part that makes dog’s sense of smell so much better?
Jacobson’s organ (detects and identifies smells)
dogs can detecr substances at concs… lower than human
1000-100mill x
hearing: (compare to human)
15-40,000 Hz (humans 30-30,000Hz)
can hear over 4x human
taste:
bitter, sweet, salty, sour
1500 dog vs 9000 human buds
DEFINE: mixed breed
one or more parents of mixed breeds
e.g. Heinz 57
DEFINE: crossbreed
bred from parents that are both recognised breeds
e.g. Cockerpoos – Labradoodles – Puggles - Jugs
DEFINE: purebreed
both parents are same breed
e.g. Labradors – Retrievers – Boxers – Poodles
DEFINE: pedigree
purebreed that is registered and known = HISTORY OR ANCESTORS - documentation
e.g. (same as purebreed breeds but with papers)
Labradors – Retrievers – Boxers – Poodles
