How often should I deworm?

Should I treat all my pets?

Worms spread easily between pets that share a yard or bedding, so many owners treat every pet in the home. Ask your vet if you are unsure.

When should I call the vet?

If your pet is weak or pale, has blood in the stool, keeps vomiting, or a very young puppy or kitten seems unwell.
