I've been cooking my dog's food ever since I took her to the vet the first time and my vet encouraged me to try it. And I've found a really simple way to do it!

I start with finding some of the cheaper meets at a grocery store (for me in southern California, I use Von's). I especially like buying the hearts/livers, gizzards, ham hocks (pig's feet) and other unpopular meat items that are >$5. I'll put any and all meats into the crock pot. I'll cut up 1 or 2 sweet potatoes OR add one cup of dry brown rice. After that, I'll chop up 1 or 2 carrots (regular carrots, not baby carrots). I fill it with water until the water is just above all the food in there. Put the crock pot on low for 8 hours.

Oh sometimes I add a little basil or oregano, to give it flavor.

I never give my dog just the homemade food. I supplement it in with her dry kibble. This helps me cut down on costs and also introducing human food, then back to just kibble, then back to human food... it gives her the runs :/

I think the two answers are above are great. In my experience, dogs (and especially puppies) respond exceptionally well to routine. If you walk your dog regularly and consistently, your puppy will develop natural urges to urinate and the routine will help the dog understand when the appropriate time/place is.

Having a puppy is pretty time-consuming because they require a lot of attention. The habits you reinforce in their early life (from snuggling to up on the furniture to feeding them table scraps to regular walks) will likely stay with them forever. If it were my puppy, I'd try walking him (or her) three or four times a day to try to get a routine down.

I hope this doesn't sound too redundant or trite, but have you tried exercising the dog? I mean, you know, a pretty good amount of exercise. Usually a tired dog is a happy dog!

The anxiety the dog feels will likely override fatigue, but probably not for long if the dog is tired enough. Just a thought :D
