Not to be missed, BBCs Hozizon, The Secret Life of Dogs.
Not a lot new in this but it puts a lot of dots together.
Dogs are basically infantile wolfs, in the sense that we selectively breed their natural wild instincts out of them, and replaced them with the things we liked.
In a lot of ways Mankind is much more dog like than chimp like, we hunt in packs, identity and social networks are very important to us.
I like cats too, in many ways they are a lot smarter, this one likes walking on the lead with her doggy mates.
