While your Shih Tzu can't just speak up and tell you when they aren't feeling well, there are still signs and symptons that you can watch for to determine if your pet is ill. These four symptoms may be indications that your pet is sick and needs to visit the vet.
1) Eating Grass:
Does your Shih Tzu eat grass? While it's not usually normal for pets to eat or nibble grass, a small percentage may actually just enjoy the taste. If you witness your pet eating grass, watch for other symptoms to accompany this action. Are they eating normally? Have they been vomiting? Do they seem to be acting differently? If your pet continues to consume grass and shows other symptoms, a trip to the vet may be necessary.
