PetArmor Plus provides fast protection for dogs, combining fipronil and (s)-methoprene to kill adult fleas, flea eggs, flea larvae, ticks and chewing lice.

The flea and tick preventative should be used monthly to provide optimal protection. Because fleas and ticks can be present year round, even in colder climates, and can lay dormant for several months before hatching, the Companion Animal Parasite Council recommends treating your pet each month throughout the entire year. Used a directed, PetArmor Plus can stop infestations and help prevent reinfestation. Apply PetArmor Plus topically only on dogs and puppies over 8 weeks of age.

PetArmor Plus is available in four different packages for different sized dogs: 4-22 lbs., 23-44 lbs., 45-88 lbs., and 89-132 lbs. Please do not attempt to adjust your dog’s dose on your own.

It controls mites that may cause sarcoptic mange and kills deer ticks that can transmit Lyme disease. It also kills brown dog ticks, American dog ticks, and lone star ticks and prevents flea reinfestations for four weeks.

Can I apply the product right after I bathe my pet?

How often can I apply PetArmor Plus?

You should not reapply the product any more often than once every four weeks.

The products made my dog’s hair greasy at the application site. Should it do this?

Once the product has dried on your dog’s skin, the application site should not appear greasy. However, if some of the product did get caught in your dog’s hair it could cause a greasy appearance. If the dog’s hair still appears greasy 48 hours after application, we would recommend using a wet washcloth or paper towel to wipe the excess product off the fur.

I have a cat that plays closely with and/or grooms my dog. Will this product be ok to use?

Yes, it is ok to use this product if you have a cat in your home. We do recommend separating your pets until the product has had a chance to dry for 24-48 hours. This will help to reduce the chance of your cat grooming and ingesting the product off of your dog.

This product has a shelf life of three to five years. When properly stored and under ideal conditions it will be five years. If there has been a variance in temperature (extreme heat for example), it may reduce the effectiveness of the product.
