Dog vomiting & diarrhea after kennel: Is it stress? What to do?

Updated on September 23rd, 2025

Pet's info: Dog | Shih Tzu | Female | spayed | 4 years and 4 months old | 11 lbs

My dog stayed in a daycare kennel all weekend, she got home last night and threw up everything she had ate and tried to drink water and threw that back up. Her stool is runny also and every time we go outside she tries to poop and nothing comes out...can I give her any over the counter medicines or what can I do to help with her upset stomach? Could this be stress causing this??

Poor Addie! Stress can certain cause an upset stomach in some dogs, so it's possible that this could be the problem given that she just returned from a boarding kennel.

If she is acting normal otherwise, you can try withholding food for the next 12 hours to give her stomach a chance to settle, then feed a bland diet of plain boiled chicken and rice for the next 2-3 days until things are back to normal. I'm afraid that by law, we cannot recommend any kind of medication for any pet (even over-the-counter meds) without an exam - but I can tell you that I don't find any OTC meds particularly helpful for GI upset in dogs. Withholding food and a bland diet are usually the best things to do :)

If she continues to vomit even though her stomach is empty, or if she develops any other symptoms such as acting lethargic or not wanting to eat, I would recommend taking her to the vet for treatment as these can be signs of a more serious problem.

Why is my dog vomiting, has diarrhea, and won't eat after boarding?
Thank you for submitting your question regarding Kairi. She may have been stressed by her change in environment while you were out of town. This can set off a bacterial imbalance in her gastrointestinal tract resulting in vomiting and diarrhea. I recommend that she sees her veterinarian today to see if this is the case. She will likely require fecal testing and some form of treatment depending on these results and her exam findings. She may receive an antibiotic, an anti-nausea medication and possibly fluid therapy. I hope this information helps!

Dog sick after treat: diarrhea, vomiting. Can I treat at home?
Poor girl. This certainly sounds like an upset stomach situation. You can try a few things today to see if she improves. 1) Bland diet- boiled plain chicken or lean ground turkey and white rice 2) Probiotic- over the counter Culturelle from your local pharmacy can help restore the normal GI flora 3) Fiber- add 1-2 tsp of canned pumpkin (not the pie filling) in her food daily As long as she remains active, does not start excessively vomiting and still has a good appetite, you can try these things for the next 24 hrs or so and see if she gradually improves her condition. I hope that your fur baby Mia is able to recover well from this upset stomach episode. : ) Best of luck moving forward and take care!

Vet Q & A
My dog is vomiting and has diarrhea. Stress or did he eat something?
If you caught him chewing on something today, my concern is that he chewed up something else at an earlier time and may have a foreign body or toxicity. Stress can certainly cause vomiting and diarrhea in some situations but in a puppy that is used to being left alone, I am more concerned about foreign body, parasites or viral disease. If he is active and alert you can feed small frequent meals of his regular dog food (just a handful at a time every couple of house) if no vomiting then continue to monitor. But if he is depressed, won't eat or vomits up what he does eat then I strongly recommend a vet visit today. I hope Budleigh is feeling better soon.

What to do if my dog is vomiting and has diarrhea from bad water?
Diarrhea and throwing up can have many causes. It is basically a problem with the stomach and intestines caused by a food over sensitivity, eating something that does not agree with the dog, intestinal parasites, bacterial infection, viral infection, the weather, food change, stress, etc.  I would fast Annabelle for 12 hours and then put her on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to her regular food slowly over a few days. If this does not clear up the diarrhea or if the vomiting increases, or if she gets lethargic, she needs to see a veterinarian for an exam as there may be something more serious such as an infection going on

My dog has diarrhea after boarding. Is it safe to wait for the vet?
I think it is safe to wait. I would do the canned pumpkin and bland food for a day or two. It's likely to be stress colitis, but a quick exam with the vet is a good idea. You can also start probiotics which may help her GI tract get back to normal quicker.

My dog has diarrhea & vomiting after new food. What should I do?
Unfortunately, it is quite common for some dogs to experience GI upset ([vomiting](https://www.petcoach.co/dog/condition/vomiting-1/) or [diarrhea](https://www.petcoach.co/dog/condition/diarrhea-1/)) when switching food. As long as Bo is behaving normally otherwise, you may be able to [manage her at home](https://www.petcoach.co/article/6-things-you-can-do-at-home-if-your-pet-has-diarrhea). I recommend withholding food for 12-24 hours. Resume feeding a bland diet (boiled boneless/skinless chicken breast mixed with plain cooked white rice) in small, frequent amounts. Begin with 1 tablespoon of food every hour and gradually increase the amount as long as she doesn't vomit. Feed the bland diet until the stool is consistently normal (usually several days), then transition slowly to the new diet over another 5-7 days. [Veterinary probiotics](https://www.petcoach.co/article/probiotics-and-prebiotics-bacteria-aren-t-all-bad) may be considered to promote gut health. If she continues to vomit and have diarrhea, or develops lethargy, loss of appetite, or abdominal pain in spite of a bland diet, she will need to see a vet as soon as possible.

Why is my dog vomiting and having diarrhea after vacation?
Poor Merida! The vomit looks more like regurgitation, or indigested food. Her nose scratch may be from digging to get out of her crate. All of her symptoms may be caused by separation anxiety, especially because she is behaving differently or if this is the first time you have left her. However, this can be coincidental with parasites, an infection, or ingestion of a toxin or foreign body. I recommend keeping a close eye on her and having her seen by a vet if she develops bloody diarrhea, continues vomiting, or starts acting lethargic. You can hold off food for the rest of the day and give small amounts of water. I hope this helps!
