— Preventatives —


Preventing parasites is an important part of overall wellness for both cats and dogs.  In the same way that proper vaccinations prevent illness, you can expect quality preventive products to be much less costly and easier on your pet than treating problems resulting from parasites.


We carry a wide range of preventatives in our clinic for dogs and cats, puppies and kittens.  If your pet currently is not being treated, or if you are interested in updating your preventive program, please contact us to discuss the best options.

These products and many other items may be ordered from the Prescription Refills page or through our Pet Portal website
