Yorshire terrier shedding more than normal? ?

A veterinary visit is probably a good idea - you have to be careful with homemade diets. Dogs need vitamins and minerals in certain proportions and homemade diets are often lacking or have something in excess. Dogs will not starve themselves, if you leave him with his bowl of food, he will eventually eat it - but he'll try to hold out because he likes your food better! He sounds like a pretty smart puppy. Dog foods are formulated to meet specific requirements, and are nutritionally balanced for dogs. There are plenty of brands and varieties available, try http://www.dogfoodanalysis.com/ for a good brand. We can't diagnose your Yorkie over the internet, he may have an underlying illness, only a veterinary examination can determine the cause of the shedding. Be sure to tell them about your homemade diet, chances are that your veterinarian can help you balance it if you so choose to feed him this way. Sometimes thyroid problems also lead to a dull coat and hair loss.

Yes, this breed does shed quite a bit. About the urine, it might just be normal that the dogs urine smells strong, but you could also call your vet and ask them about it, just to be sure.
