What is wrong with my doggies?

Go to the vets… My dog does it a lot when she drinks too much and tries to hold it in for me til I can get her outside… Do you mean randomly as in weekly or like just once every few months?! because if its quite regularly then GO TO THE VET… if not… try to watch whether they drink too much or like krads said they might have a sensitive stomach… =) x

your dogs may have sensitive stomachs, try boiling white rice along with a small amout of boiled white chicken breast pieces mixed in, when their having bouts of vomiting. give them only a few tablespoons at a time then with hold food for a few hours, if they hold that down, you can give them alittle more. dont be afraid to not feed them for several hours when their stomachs are upset. are you sure their not eating something in your yard or possibly food from the garbage can in your house while your gone? watch for this it may be upsetting their stomachs. also you can buy sensitive stomach formula food from the pet stores. remember, small amounts of food at a time.

call a vet, this may be serious,

or, they could be tricking you and it is just fake vomit they put there for a joke
