Why is my dog shaking, whining, and struggling to poop after vomiting?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 5 years and 9 months old | 51 lbs

My 5 year old male dog started vomiting, which has now stopped. He now has tried to have a bowel movement multiple times, but all that comes out is air and a few drops of liquid. He is also shaking. His tail is wagging, and he doesn’t seem to be in any pain. I’ve pressed on his abdomen, and I don’t feel any lumps/masses, and he doesn’t act like it hurts. His nose is cold and wet. His food has not changed. He has been drinking and eating. The only odd thing is he has been whining.

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear Shadow is feeling under the weather. GI upset can be due to a variety of causes, including intestinal parasites, dietary indiscretion, foreign material ingestion, or another underlying medical issue. If Shadow's energy level is normal and he is able to keep down water, I would recommend withholding food until the morning and then starting small amounts of a bland diet (white meat chicken with white rice, for example). If this does not improve his signs within 24-48 hours, then I would recommend he be evaluated by a veterinarian. If the vomiting and diarrhea worsen, he starts acting lethargic, becomes inappetent or you are concerned, then I would recommend he be seen by a veterinarian, have any necessary testing done (xrays, bloodwork) and start any treatment (fluid therapy, anti-diarrheal, anti-nausea medication) that he may need to feel better. Good luck!
