Hi, everyone! I’m new here with a now nine week old Pembroke! I’ve had him for a little over a week and he’s extremely well-behaved and awesome, but we’ve already had a couple of issues. His breeder had him on Taste of the Wild puppy formula and we planned on feeding him that until 12 weeks, at which point we would be slowly introducing Blue Buffalo chicken and rice. Sadly, nowhere (without exaggeration) around here sold it after we quickly ran out of the amount the breeder sent with him. He had no slow introduction to the new food and he had diarrhea and vomited once. We took him to the vet (this is my first puppy so I’m really erring on the side of caution) and they ran some tests due to my worry of taking him outside in my backyard to use the bathroom. I live in a condominium and I don’t have a blocked off backyard, but there hasn’t been parvo in the area and it takes a LOT of work for a dog to get into my backyard despite there being no fence. Even then, I worry about him catching something. They said he’s fine – gave him some antibiotics while he adjusts to the new food and he’s been fine. His poop was normal yesterday, but we left him with my boyfriend’s grandparents today and now it’s toothpaste consistency. She informed us she gave him a bit of cheese, two potato chips and a Cheez-It. He also snuck a few bites of her dog’s food, the adult version of what we feed him. We got home from a 50 minute car ride and he vomited about 15 minutes after we got home. I would usually attribute it to carsickness, but he’s never had an issue in the car before. I’m a bit worried. He’s acting relatively normally (biting the daylights out of my sister) not lethargic at all… Should I be concerned? I don’t want to pay for another $100 vet visit if I don’t need to.
