We thought he'd rehome the puppy in Episode 1 who peed on him
Or one of Nancy's puppies.
But he left EMPTY HANDED 
I know if he got another pup it makes it look like he just randomly buys puppies.
But he's got 4.
He's got a farm.
He couldn't got another (not even a puppy, a small terrier)
But not the beagle, mad as a box of frogs.
