Most dogs with COVID-19 recover fully with basic home care: fluids, rest, and good nutrition. The illness is typically mild in dogs, and serious complications are rare. Still, knowing what to watch for and how to keep your dog comfortable can make a real difference during recovery.
Symptoms to Look For
Dogs infected with SARS-CoV-2 don’t always show obvious signs. In a study of pets from confirmed COVID-positive households in Germany, only about 42% of infected animals showed any clinical signs at all. When symptoms do appear, the most common one is simply an increased need for rest, followed by diarrhea and reduced appetite.
Respiratory symptoms like coughing, nasal discharge, and labored breathing occur in roughly 18% of positive dogs. Diarrhea shows up in about 13%. You might also notice your dog seems less energetic than usual or isn’t interested in walks, toys, or food. These signs overlap with many other illnesses, so a dog that’s been around a COVID-positive person and starts showing symptoms is worth monitoring closely.
Home Care That Helps
The American Veterinary Medical Association recommends supportive care as the standard approach: ample fluids, good nutrition, and rest. There’s no specific antiviral treatment prescribed for dogs with COVID-19, so your goal is to help your dog’s immune system do its job.
Keep fresh water available at all times. Dogs with diarrhea or reduced appetite can become dehydrated quickly, so encourage drinking. If your dog won’t eat their regular food, try warming it slightly to make it more appealing, or offer bland options like plain boiled chicken and rice. Small, frequent meals are easier on a dog with an upset stomach than one large serving.
Let your dog rest as much as they want. Skip long walks and vigorous play until symptoms resolve. A quiet, comfortable spot away from household commotion helps. If your dog has nasal congestion, running a humidifier nearby can ease breathing.
Never Give Human Medications
One of the most dangerous things you can do is reach into your own medicine cabinet. Ibuprofen (Advil, Motrin), naproxen (Aleve), and acetaminophen (Tylenol) are all toxic to dogs. These drugs are processed differently in a dog’s body: they last longer, reach higher blood levels, and are absorbed faster through the stomach and intestines.
The consequences can be severe. Ibuprofen and naproxen can cause stomach ulcers, intestinal perforations, kidney failure, and liver failure. Acetaminophen causes dose-dependent liver damage in dogs, meaning the more they ingest, the worse the outcome. Even aspirin, which veterinarians occasionally prescribe in carefully controlled doses, is unsafe to give on your own. If your dog seems to be in pain or running a fever, call your vet rather than medicating at home.
When Your Dog Needs a Vet
Most cases resolve without veterinary intervention, but certain signs warrant a call or visit. Labored breathing that doesn’t improve with rest is the biggest red flag. Persistent refusal to eat or drink for more than 24 hours, bloody diarrhea, extreme lethargy where your dog won’t lift their head, or pale or bluish gums all signal that something more serious may be happening. Secondary infections from bacteria or other viruses can develop alongside COVID-19 and prolong illness, so worsening symptoms after initial improvement also deserve attention.
If you do contact your vet, mention that someone in the household has tested positive for COVID-19. This helps the clinic prepare and take appropriate precautions.
Isolation and Timeline
The CDC recommends keeping a COVID-positive dog isolated from other pets and limiting contact with people outside the household. Your dog can return to normal activities once they’ve been symptom-free for at least 72 hours without medical treatment, and either 14 days have passed since their last positive test or follow-up tests come back negative.
For most dogs, the active illness lasts roughly 2 to 10 days. Some dogs carry the virus for much longer, potentially up to six months, without showing symptoms. During isolation, keep your dog in a designated area of the house, avoid dog parks and pet stores, and wash your hands after handling them.
Testing and Diagnosis
Getting a dog tested for COVID-19 isn’t as simple as picking up a home test. The decision involves coordination between public health and animal health officials. A dog is considered a suspect case when it has an epidemiologic link to a confirmed human COVID-19 patient and is showing compatible symptoms. Testing involves swabs (nasal, oral, or rectal) analyzed through PCR, and all confirmatory testing is performed at the National Veterinary Services Laboratory.
In practice, most vets will treat the symptoms rather than pursue formal testing unless there’s a public health reason. If your dog is mildly ill and you’ve had COVID recently, the connection is fairly clear, and testing won’t change the treatment plan.
Risk of Spreading It Back to You
The risk of a dog passing SARS-CoV-2 to a person is low. The CDC states there is no evidence that animals play a significant role in spreading COVID-19 to people. The rare documented cases of animal-to-human transmission involved farmed mink, white-tailed deer, pet hamsters, and one cat, not dogs. You are far more likely to catch COVID from another person in your household than from your pet. That said, basic hygiene still makes sense: wash your hands after contact, and avoid letting a sick dog lick your face.
