I found three infographics about canine anatomy on Pinterest. IMHO, they are very informative … they are also too big to put together, which is why this is ‘pt.1’. Today, Part 1 ,covers skulls and spine (neck to tip of tail). Tomorrow,part 2 will focus on teeth, paws and movement. On Thursday, Part 3 will share an old poster of a dog’s muscular system and internal organs.
