Why does my shih tzu get smelly so fast? And why does he keep biting himself. He doesn't have fleas or ticks. Thank you!

A yeasty or very strong "doggy" smell is often caused by a skin condition such as allergies or a skin infection of some kind - this would also explain why Max is biting himself so much, since many of these conditions also cause itching. You can try bathing him in a medicated shampoo for yeast and bacterial infections, such as Malaseb or Keto-Chlor. If this doesn't help, I would recommend having him examined by a vet when you are able to as he will probably need prescription medication - he/she can do a simple test called a skin scrape to help determine the problem and get him started on appropriate medication to treat it.
