Let’s see where they fit on the phylogenetic tree!

Here’s a link to the full version because i think tumblr is gonna make this one impossible to use: https://whyevolutionistrue.wordpress.com/2011/10/31/a-new-phylogeny-of-the-mammals/#jp-carousel-47554
And here is a version with dogs, cows, and horses very hastily highlighted!

As you can see here, if you trace back equidae (horses), bovidae (includes cows), and canidae (dogs), equidae and bovidae share a more recent common ancestor than either of those groups and canidae- so horses and cows are closer than either of them to dogs!
