It does appear the Mia may be feeling it a bit off, but I wouldn't get too worried just yet. It could be the weather if it's warm where you are, so she could be generally unwell. Given that she did eat and had some water, I wouldn't take her into a vet just yet. Keep an eye on her over the weekend, and if she's still acting off on Monday, then have her seen by a vet on Monday. If she develops other symptoms such as vomiting, diarrhea, stops eating, and/or stops drinking, then I would be worried and bring her into a vet sooner. I hope this helps and she feels better soon!

    Hi there! Sorry to hear that Mia 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 Mia 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 medications to make her feel better. Good luck! Keeping my fingers crossed for your girl!
