K9 Advantix II - Best-selling comprehensive flea & tick protection

K9 Advantix II provides comprehensive monthly protection for dogs against ticks, fleas, mosquitoes, biting flies and chewing lice. That's why veterinarians recommend K9 Advantix II to repel and kill all life stages of fleas (eggs, pupae, larvae, and adult fleas) and ticks (Deer ticks, American dog ticks, Brown dog ticks, and Lone Star ticks).

Advantage II - Monthly topical flea prevention

Monthly topical flea prevention with Advantage II makes it easy to protect your pet from fleas, while working to effectively break the flea life cycle by killing flea eggs and larvae.

Advantage Multi - Combination heartworm & flea prevention

Protecting your pet with Advantage Multi is an effective way to prevent heartworm infection, while at the same time killing fleas, treating hookworms and roundworms, and more.

Alternative flea & tick protection and treatment

If you are looking for long-lasting flea and tick prevention, Seresto collars can provide your pet with a full 8 months of continuous protection. To quickly kill and remove biting or attached ticks without the use of conventional pesticides, try Resultix spray.

Advantage Spray - Flea protection for home and yard

Prevent re-infestation of fleas in your yard and around your home with the safe and effective Advantage line of home flea infestation control products.

Joint care

Many pets suffer from arthritis and joint pain, making even simple activities like walking and playing painful. Many veterinarians recommend Quellin for dogs to help relieve joint pain and inflammation. To help support joint health, give your dog SynoviG3 or SynoviG4 Soft Chews with Glucosamine, MSM, Creatine, and Perna Canaliculus.

Gastrointestinal worm treatments

Bayer also offers prescription medications to combat gastrointestinal worms, such as tapeworms, roundworms and hookworms. Ask your veterinarian which one is right for your pet.

Bayer offers several effective ways to combat bacterial infections in pets, including Baytril Taste Tabs for various internal and skin infections, Baytril Otic for bacterial ear infections, and Malaseb Shampoo for bacterial skin infections.
