I am new owner of an eight week old female German Shep. Tonight she has thrown up three times in her crate. I have had her since this past Friday(today is April 14th). She has been a happy pup until tonight. I really have no idea what to make of it. I have not changed anything I have been doing. I am feeding the same food the breeder was. I am very worried at this point. I have a vet app. for this friday. Should I try to move it up? Any advice for this new owner is greatly appreciated.
