I have a staffy x pitty she is about 8 months old and she is usually very playful but she won't eat or drink anything and just lays around she not herself and I'm worried, this is my first dog and I'm not sure what to do or how much vets cost please help ?

It doesn't matter what the vet will cost, if your pet is not acting normal (has he had vaccinations?)' you will have to find out why and take him in.

At 8 months ANY breed will be active and playful, this breed especially. I would also like to know if she is up to date with vaccines? The thing with dogs and puppies is they can hide their illnesses very well, when they start showing symptoms it's usually something medical. Even if we could diagnose her, you need to get her into the vet for proper medical treatment. You can be expected to pay anywhere from $60-$200.
