Pet's info: Dog | German Shepherd | Male | unneutered | 1 month and 23 days old | 7 lbs

My new puppy won't eat anything and hasn't eaten in two days. He has vomitted and has diarrhea, and will only drink water. He's been laying down all day and only gets up to go to the bathroom. Should I be worried? or is this him getting used to his new life and being nervous still

Unfortunately, this is not normal behavior for a young puppy and is pretty concerning. At less than two months old, your puppy needs to eat regularly or he risks having low blood sugar, which can cause serious health problems. Vomiting is not typically caused by stress and all these signs make me worry about a more serious illness. Please have him seen by a veterinarian right away because his lack of appetite and vomiting are very serious.
