So Remi is home and doing well, but boy is this puppy stuff exhausting! I need to be able to leave him in his crate (which he hates) for 15-20 minutes each morning and afternoon to run the kid to/from school so we're starting with kongs. Today he had 2 with just dry kibble in it, the first time he got about half out and I helped him with the rest, the second time he was in the kitchen (so more room to scoot it around) and got all but a few bits out. So, he's obviously a newbie and probably not ready for all the fancy frozen ones. What's the next logical recipe? Also, how messy are these, am I going to have to change his bedding after he has one?
