Deworming Services for Pets

Deworming is an essential part of your pet’s preventative and protective care. It helps to reduce their susceptibility to internal and external parasites. Please feel free to contact our team if you have any questions about your pet and their deworming treatments.

What is a deworming schedule?

Basically, this is a series of medical treatments to help prevent the transmission of worms and worm eggs. The prescription medications are usually taken orally, and can be in tablet or liquid form, depending on you and your pet’s preference.

How often should my pet be dewormed?

Deworming needs to be a constant and routine part of your pet’s health care through all stages of their life. Initially, deworming is done in puppies or in kittens, so they are protected from a young age. Once they reach adult age, dogs typically need to be dewormed every 3 months after they are 6-months-old in order to maintain protective effects.

What are some types of parasites found in cats and dogs?

Roundworms, hookworms, tapeworms or whipworms – which are often too small to see with the naked eye – are the most common types of parasites to infect our loyal companions.

If my cat or dog has worms, what symptoms should I look for?

Common symptoms of intestinal parasites include diarrhea, soft stools, foul odour to the stool or irritation around the rectum. That being said, there are many patients who show absolutely no symptoms, especially in the early days of infection. For this reason, it’s important to regularly take your pet to their veterinarian, so they can be fully examined.

Are there any side effects from deworming medication?

The most common side effect would be mild gastrointestinal upset, although this happens in a very small number of patients. If you think that your dog, cat or other pet is experiencing an adverse reaction to their deworming, please contact our practice as soon as you are able and we would help you as quickly as possible.
