How do you know if your pet is sick? Here are the signs
August 29, 2022

It’s important to know the signs of a sick pet. If you suspect your pet is ill, take them to the vet immediately.

The following are general signs of sickness in animals:


Coughing and Sneezing

If your dog coughs or sneezes, see a vet immediately. It could signify an upper respiratory infection, which can be serious if left untreated. Vets will take X-rays and perform blood tests to determine what’s wrong with the animal. Treatments include antibiotics and antivirals, depending on the type of infection.

Lethargy and Lack of Interest in Daily Activities

A sick pet may not be able to get up or play as much as usual because they are uncomfortable or have pain. A sick animal may even lose interest in food and water, a sign that something more serious is happening. If you notice any changes in your pet’s behavior, don’t wait for them to get worse before taking them to the vet for treatment. It could be too late at that point.


Watching their attitude and behavior is the best way to tell if your pet is depressed. It could signify something wrong with them if they’re not as happy or playful.


A high fever can signify many different things in dogs, from an illness to a vaccination reaction. If you think your dog has a fever, contact their vet immediately.

Vomiting or Diarrhea

This is another common sign of disease in dogs and cats alike, but it can also be caused by seasonal allergies, parasites, food allergies, or even stress. If your pet is vomiting or having diarrhea frequently, it could mean that they have an illness and need medical attention immediately.

Excessive thirst

This is a very common sign of illness in dogs. The dog is drinking more than usual, which can be due to increased water intake or stool production. If your dog drinks more than usual and has diarrhea, it may be due to an infection or irritation of the GI tract.

Weight loss or gain

Weight loss or gain is one of the dogs’ most common signs of illness. If your dog has lost weight, keep an eye on his diet and ensure he is getting enough exercise.

Some dogs are naturally thin, but others may be underweight because of illness or a sudden change in their diet. If your dog has recently lost or gained weight, it’s a good idea to take him to the vet for a checkup.


A pet with difficulty passing solid waste through its bowels may have an illness. If a pet’s digestive system is not functioning properly, it can lead to serious health problems or even death.


To be sure, cats and dogs can get sick even when given the best care possible. Some things just can’t be prevented, but there are certain signs you should keep an eye out for. If your pet suffers from any of the most common pet illnesses, it’s important to seek a veterinarian quickly. The sooner you come in, the more likely it is that your pet will make a full recovery.
