Why is my Shih Tzu vomiting? Is it his food or too much exercise?

Updated On September 23rd, 2025

Pet's info: Dog | Shih Tzu | Male | neutered | 7 months and 23 days old

Hello, my 8month old shihtzu keeps vomiting, i have my shihtzu on pedigree wet canned food mixed with pedigree biscuits I’m worried I may be over feeding him or over walking him. I take him for an hour walk each day then one big walk ones a week maybe 2/3 hours just in parks where he is able to run around. could I be exhausting him or over feeding him causing him to vomit. He doesn’t seem tired after the walks as he still runs around. Need advice on nutrition/excersise or whyyouthinkheisvomiting

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your questions. The amount of exercise you are currently giving Hugo should be just fine and is not in any means excessive. The vomiting could be due to the food so I would consider switching his diet altogether and see if this helps. Many cases (roughly 65%) of vomiting / diarrhea can be directly related to the diet or an imbalance of the normal intestinal bacteria. If Hugo is otherwise healthy but vomiting, I would recommend changing his food to something such as Science Diet or Royal Canin and feed this for 4 weeks. If he continues to vomit or worsens, I would have a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
