My 7-week chihuahua puppy is sick: tired, vomiting, not eating, no poop.

Pet's info: Dog | Chihuahua | Female | unspayed | 1 month and 18 days old

Hello we have just gotten a 7 week old chihuahua puppy today. She has been very tired, can’t seem to poop and seems to strain when trying, throws up every so often, and does not want to eat at all. She isn’t very energetic and seems restless. I’m very worried about her. She is a very small puppy.

Hi there! Sorry to hear that Bella is not feeling well. The clinical signs you describe are concerning when they occur in a puppy as they can be seen with serious gastrointestinal infections such as Parvovirus. Other possibilities include intestinal worms and dietary indiscretion, among other possibilities. The sooner these conditions are treated the better the outcome tends to be. For this reason, I recommend that you have Bella evaluated by your veterinarian to check for these possibilities and to start therapy based on findings. At the very least they can address dehydration if present and start her on anti-nausea medications. Good luck! Keeping my fingers crossed for your girl!
