Interceptor Worm and Heartworm Control Treatment for Dogs
Interceptor for Dogs is a monthly flavored tablet formulated to help protect dogs against heartworm disease and several common intestinal worms. Powered by milbemycin oxime, this convenient oral treatment helps prevent heartworm disease while treating and controlling hookworms, roundworms, and whipworms. The palatable flavor tab is readily accepted by most dogs, making monthly parasite protection simple and stress-free. Suitable for dogs and puppies from 4 weeks of age and weighing at least 2 lbs, Interceptor offers reliable broad-spectrum internal parasite protection in a single monthly dose.
Why It Stands Out
- Helps prevent heartworm disease with monthly administration
- Treats and controls hookworms, roundworms, and whipworms
- Broad-spectrum internal parasite protection in one tablet
- Contains milbemycin oxime, a trusted active ingredient
- Palatable flavored tablet accepted by most dogs
- Simple once-monthly dosing schedule
- Suitable for puppies from 4 weeks of age and weighing at least 2 lbs
- Available in weight-specific strengths for accurate dosing
What It Covers
Interceptor for Dogs helps protect against:
- Heartworm disease (Dirofilaria immitis)
- Adult hookworms
- Roundworms
- Whipworms
How the Formula Works
Interceptor contains milbemycin oxime, which works by eliminating immature heartworm larvae before they can develop into adult heartworms. It also treats and controls common intestinal worms by interfering with their nervous system function, helping remove existing infections and maintain ongoing protection when administered monthly.
