My 5month old Shih Tzu puppy started throwing up since Saturday night at 1st it was yellowish pale in color & today he threw up again but this tim it was foamie white. All 2days he has been hardly moving totally not being himself. He also has not ate anything. Please help if you have had this experience with a shih tzu thank you!

When my dogs are near toads they spray out white foam from their mouths to stop the poison going in if you dog is doing that I guess it may have been poisoned by one and mabe the sleeping might be apart of it too
Best of luck to you and your dog

Throwing up white or yellow foam on occasion is relatively normal, but if they are doing it continuously and not eating then it's time for the vet I'm afraid.

There are really too many things that could be wrong for us to guess.

Are there any other symptoms other than vomiting and being lethargic?
Is he still drinking OK?

He's been throwing up, more now I found dirty toilet paper under the place he likes to hide do you think he's stomach is just upset. He has not drank anything nor ate since last night. Now he had one bawl movement but it was really brown.
