Parasite Prevention

Dogs and cats are at risk for a number of parasitic infections, and many pet parasites can infect both animals and people. A monthly preventative is important for both the health of your pet and your family.

Fleas and Ticks

Fleas and ticks can make your pet very uncomfortable and transmit bacteria and disease. If you notice signs of fleas and ticks on your pet, our veterinarians can help you effectively treat the problem and prevent it from happening again with a monthly preventative.

For dogs, Simparica and Nexgard are guaranteed and available exclusively here at Sierra with a prescription from our doctors. Both chewable tablets are great tasting preventatives that kill adult fleas before they have a chance to lay eggs, prevent home flea infestations, and kill three common types of ticks.

For cats, Revolution Plus provides 6-in-1 continuous protection against fleas, ticks, heartworms, ear mites, and other parasites. Whether your cat is indoor-only or outdoors, the simple-to-apply topical solution interrupts the flea life cycle before adult fleas have a chance to lay eggs, kills ticks, and is highly effective in preventing heartworm infection and ear mites.

An annual parasitic disease screen is recommended for every annual visit, and screens your pet for a broad spectrum of parasites to make sure they’re free from heartworm, lyme disease, and other diseases.

Heartworm is a serious and potentially fatal disease that can affect all pets, even indoor dogs and cats. The disease is caused by heartworms, foot-long worms that live in the heart, lungs, and blood vessels of affected pets. It only takes one bite from an infected mosquito to transmit heartworm disease, and pets can become infected at any time of year.

Monthly heartworm preventatives for cats and dogs or the 6 month ProHeart injection for dogs are essential to protect your pets from heartworm disease. When dosed on time, 12 months a year, the monthly heartworm preventatives disrupt the heartworm life cycle.

If you have a busy schedule or travel frequently, the 6-month shot is a great option for dogs. Simple and convenient, just 1 shot provides your dog with 6 months of continuous heartworm protection.

A yearly heartworm test is required for every annual visit to confirm that your pet is heartworm-free and that your prevention program is working.
