Here's a Puppy Fix for you. This is the litter of Treeing Walker Coonhounds that I raised last season:
Every batch of puppies I've raised (27 so far!) always have to be touching one another when they're sleeping. I guess being crammed together in the womb for many months makes them want to do that? We kept a male and female from this litter; the other four were sold to local hunting friends and reports are that they are all doing outstanding work for their new owners, hunting raccoon and black bear.
