8 Ways to Tell If Your Dog Is Sick

by Amy Smith - 6/6/19

It can take a bit of detective work to determine if your dog is sick or running a fever. Dogs instinctively hide their discomfort. You may not notice symptoms at first, as your dog might be avoiding you if he feels unwell. Also, of course, your dog can’t just tell you what’s troubling him. You don’t want your furry friend to suffer for long, so watch for these clues that he is feeling under the weather.

1. Prolonged vomiting and diarrhea

t’s pretty common for dogs to vomit from time to time — after eating too much, for example, or eating something that disagrees with them, such as table scraps or garbage. Stomach upset can also cause diarrhea. Try withholding food and water for 12 hours, then offer just water. If your dog keeps that down, offer a little food and continue to monitor his reaction. If the vomiting and diarrhea persist more than 24 hours or if there is blood in your dog’s vomit or stool, it’s time for a visit to the vet.

2. Difficulty urinating

If you notice a difference in your dog’s “bathroom” habits, pay close attention.

Problems with urination warrant a call to your vet.

Another potentially serious symptom is a swollen abdomen, especially if it is accompanied by dry heaves and agitation.

Bloat can put pressure on major blood vessels and even cause the stomach and intestines to become twisted, a condition that without immediate medical attention can be fatal.

Coughing is a common symptom that may be caused by a simple viral or bacterial infection. Coughing can also signal that a foreign object is lodged in the dog’s throat. More rarely, coughing is associated with certain heart conditions. If your dog’s cough does not dislodge a foreign object, persists for more than a few days or is accompanied by heavy breathing, your dog may need to see the vet for antibiotics. Try using a humidifier at home to help ease the cough.

Your dog’s breed, size, age and personality help determine his usual level of energy and his appetite.

If he seems more lethargic than usual, is not interested in his usual games and eats much less than usual or refuses to eat at all, he may need a vet’s care.

A dog’s normal body temperature runs between 99.5 and 102.5 degrees Fahrenheit. Infection, bacterial or viral diseases and ingesting poisonous substances each can cause a dog to run a fever. You may suspect fever if your dog is lethargic, has a hot dry nose and ears, shivers or loses appetite. But the only way to know for certain is to take the dog’s temperature. This can be done rectally with a digital thermometer or you may use a dog-specific ear thermometer. If you get a reading over 103 degrees, take your dog to the vet right away. He’s sick!
