Gastroenteritis in Dogs: Causes, Symptoms, and Recovery
It can be alarming if your dog suddenly starts vomiting or having diarrhea. These symptoms often point to gastroenteritis, a common condition in dogs involving inflammation of the stomach and intestines. While many cases are mild and resolve with care, it’s important not to overlook the symptoms, as they can also indicate more serious health issues.
In this article, we’ll explain what causes gastroenteritis in dogs, how to recognize it, and what treatment and recovery typically involve.
What Is Gastroenteritis in Dogs?
Gastroenteritis is the irritation and inflammation of the gastrointestinal (GI) tract, specifically affecting the stomach and intestines. It usually causes diarrhea, with or without vomiting. While vomiting alone is less common, it can still be a sign of GI irritation. The condition can be:
Acute: Sudden onset, usually short-term, and often resolves with treatment.
Chronic: Lasts for more than two weeks and may require long-term management.
Common Causes of Gastroenteritis in Dogs
There are many possible triggers for gastroenteritis in dogs, such as:
Eating spoiled or contaminated food
Swallowing foreign objects (e.g., toys, plastic)
Exposure to toxins or chemicals
Viral or bacterial infections, including parvovirus
If you notice any combination of these symptoms, especially blood in the stool or persistent vomiting, contact your veterinarian promptly.
Diagnosing Gastroenteritis
Your veterinarian will perform a physical exam, ask about recent diet changes or odd behavior, and review your dog’s medical history. In rare cases, additional tests such as X-rays, blood work, or fecal analysis may be needed, especially if the vet suspects hemorrhagic gastroenteritis or foreign body ingestion.
Treatment for Gastroenteritis in Dogs
Treatment depends on the underlying cause. Common steps include:
Withholding food for several hours to allow the stomach to rest
Introducing a bland diet, such as plain boiled chicken and rice
Prescribed medications to reduce vomiting and control diarrhea
Fluids, especially if the dog is dehydrated—this may involve IV drips in severe cases
Special veterinary diets, available from your vet, that are formulated to soothe the GI tract
Prompt care often leads to recovery within a few days.
Recovery Tips for Dog Owners
Helping your dog recover from gastroenteritis includes:
Making sure they drink plenty of fresh water
Feeding small, bland meals during recovery
Gradually reintroducing regular food after symptoms improve
Keeping them calm and limiting activity during recovery
If symptoms get worse or new ones develop, return to your vet for follow-up care.
When to Seek Immediate Help
Visit your vet immediately if:
Symptoms persist for more than a couple of days
You see blood in vomit or stool
Your dog appears very weak or refuses to drink water
Gastroenteritis in dogs is a common but treatable condition. With quick action and the right care, most dogs fully recover. Always consult your veterinarian for advice tailored to your dog’s specific needs.
This on-line company is such a good find. They provide quality products at a good price with delivering them efficiently. Definitely recommend purchasing from them.
Two sweet girlies decided to make our deck their home. Mosquitoes are a big problem where we live and we had to get them protected. This was the best bang for the buck. I’ve ordered from 79Pets several times and while delivery is not fast it is very consistent.
As a retired veterinary technician I was extremely happy to finally see a flea and heartworm medication that actually does tapeworms too!!!!!!! This is a 1st to my knowledge....I live in a tropical climate where fleas never die so this is heaven sent.
Great price, authentic quality and reliable shipping. Shipping takes a bit longer, since it is being shipped from abroad. But still a reliable service.
After Seresto collars failed to get rid of fleas, I didn't know where to turn. I saw a post on a page I follow (Kentucky Kitty Cats) saying that they use Nexgard Combo for the cats they shelter. I decided to try it and IT WORKS!
This is Lexi Marie! She was wondering why mom was so excited for buying flea medicine. I explained to her that we saved $100 and that she would understand some day when she grows up.
Last year, I made a visit to the vet. I told them that Kattie/cat had ear mites. They gave me an ointment costing $80canadian. I used it up and purchased another bottle. $160. total not including the cost of the vet visit. No results. The ear mites have been there for a long time. Canadian vets have control of what is sold in Pet stores and you cannot purchase off the shelf products not recognized by them.
I jumped at the chance to purchase your produce with a recommended 100% effectivity. I was willing to try, but was suspicions.
After a month there was still a little scratching but after 6 weeks, the mites are gone and the scratching is gone.
Thank you very much for this mite solution. I recommend it heartily. Harry
P.S. Do not tell the Canadian vets as they will outlaw your product.
En fait, c'est le seul produit dont mon chat "Winston" ne soufre pas de problèmes cutané et perte de poils, le "Révolution plus" fait très bien le travail, merci.
