Is it normal for a dog to puke? My dog, a shih tzu, pukes regularly and I'm a bit worried about it. I've heard from other dog owners that this is a common problem with dogs especially that we are in a tropical country and a shih tzu is not so used with the hot weather. We asked the vet about this and she said it doesn't necessarily mean the dog is sick and it's a casual thing but she gave Lokii pet supplements. I just hope it helps him because the kids are worried every time he pukes.
