What is wrong with my dog?

Lots of water and grass could be so many things including a bad case of worms. I would for sure get him into the Vet’s office to be checked out.

Since you just got this dog he should have already have had an appointment set up to met his new Vet, have a check up and get any test ran for worms and such.

My pups are on a regular worm and vaccination program and see a Vet before they go to their new homes BUT the new families are REQUIRED to have the puppy set up for it’s first Vet appointment within 3-5 days, to be checked over and have a schedule set up for continuing, vaccinations, worm treatments and flea programs.

Always take a new pet into your Vet and introduce them. Get them checked over and see what the pet will need to stay healthy. This is called Preventive Medicine.

he might not like the food and he might have another source of food around the house but I would take him to the vet to get checked out

Take him to the vet! If a dog eats grass thats usually a sign that he’s sick or has an upset stomach. And he’s throwing up? That alone is enough to be concerned about!
