Has anybody ever experienced any side effects with angels eye for dogs?

My shih tzu is throwing up after two days of use. I dont know if she just has the flu but she NEVER threw up before.

No, but I would stop using it. If she continues to throw up you will know it is not the product but something else.

Dogs don't get the flu & no I don't know of anyone with problems with the product. Be certain you are giving the correct amount & not over giving. It could be possible like with some ppl, your dog could have an allergic reaction to the antibiotic or another ingredient. Stop using for a few days & see if dog improves if better then try once & if dog gets ill again, don't use again. If your dog is still ill, take to vet.
