Dog breed size versus brain size and its inferences, and canine pathology case studies

Colloquially intelligence is correlated to brain size. Although not accurate in humans, is this true in dogs? Dogs are diverse in shapes and sizes and are bred for their unique abilities and behavioural characteristics. However, during clinical MRI examinations, it was clear that although the body mass ranged from approximately 1kg to over 100kg in different breeds, the brain size did not vary drastically. This study will analyse the neurocephalic index of different breeds of dogs to evaluate if this correlates with the dog breeds’ unique abilities.
