I've had my dog for about a week and I've been feeding her dry food and can food. The second night she threw it up, I figured she just ate too fast. I stopped with the can feed until a two days later when I gave it to her once then mixed it with her dry food (kibbles and bits). She started getting the runs. I figured it could be the can food so today (Saturday) I didn't give her the can food just dry mixed with water. She ate and a few minutes later went out and pooped. She came back in and pooped again but it was mucus like and pink, it look like there was tissue in it or something. She then scooted her butt across the floor. I'm going to call the vet tomorrow and see what they can do, for now I need something to ease my mind. She drinks, she'll eat and she still runs around and plays normal like she did a week ago. She's 9 weeks, a German sharped and Golden Retriever. She ate a few bugs that she found outside and has been chewing on things but hasn't swallowed anything she chews on. She has a chew toy and she plays with that. Could it be the food she eats? Should I try changing her food? i'm trying to save a trip to the vet here because money is tight and no vets around me offer payment plans, they rather you pet die. Her poop also kind of smelled like fish, her vomit is just food no foam or anything like that. Her pee is normal as well.
