[header] How to feed your shih tzu [title] Determine your shih tzu's weight. [step] It's always best to have your veterinarian or groomer weigh the dog, since they have scales specifically created for this task. However, you can weigh your shih tzu at home with a method that is only slightly less accurate. 
Start by standing on a scale while holding your dog. Then, put the dog down, and weigh yourself again.
