What if my pet was dewormed at the breeder before I got them?
Any deworming treatments done before you got your pet were just the beginning of the deworming program. There is a huge difference between receiving deworm treatment(s) and being free of worms.
Furthermore, medications used by breeders or humane societies are not as effective as the medications we use in the veterinary hospital. Products available over the counter at pet stores are not effective, have very limited treatment ranges, are often outdated, and often have significant toxicity concerns.
There is no room for error when dealing with the health of people and our pets.
