How Does Advocate Work? 

Advocate is a monthly spot-on treatment that provides your pet with fast relief from fleas and also kills a number of internal parasites, such as heartworms. Once applied, Advocate gets working right away and all existing fleas are killed within 12 hours. Any fleas that remain in your home are then affected within 3-5 minutes of contact with your pet and die within the hour without the need for them to bite your pet. 

Advocate has two active ingredients—imidacloprid and moxidectin—both of which are insecticides that are safe for use on pets. The imidacloprid works by interfering with particular receptors in the nervous systems of lice and fleas. This leads to the parasite's paralysis and then death. The moxidectin works in a similar way by causing paralysis and death of nematodes and heartworms by interfering with the signals passed between nerve cells in the worm's nervous system. Plus, the imidacloprid is shed into the environment as your pet sheds the skin and fur, killing flea larvae within 20 minutes, which then breaks the flea life cycle.

How To Apply Advocate? 

As Advocate is a spot-on treatment, all you need to do is deposit the entire contents of the pipette onto your pet’s skin once a month. Always make sure that you are using the appropriate dosage of Advocate for your pet, as the amount per treatment will vary by your pet’s species and weight. 

Applying Advocate for Cats 

To apply the Advocate spot-on to your cat, part the fur on your cat’s neck and press the opened pipette directly onto the skin at the base of their skull. Squeeze the pipette twice or more to ensure that all the contents have been deposited onto your pet's skin.  

Applying Advocate for Dogs 

You should apply Advocate to your dog when they are standing. For small-medium dogs, Advocate should be applied in two spots, once at the base of their skull, and again between their shoulder blades. Part your dog’s fur and press the pipette directly onto the skin and squeeze to deposit the treatment. 

For large and extra-large dogs, Advocate should be applied in 3-4 spots along the dog's back from between their shoulder blades down to the base of their tail to ensure maximum coverage. 

Frequently Asked Questions

Does Advocate Need a Prescription?

Yes. Advocate is a prescription-only treatment and will require an in-date prescription from your vet in order to purchase.

Can You Buy Advocate Online?

Yes! Just because Advocate is a prescription medicine, doesn’t mean you need to purchase it from your vet. So long as you have a valid prescription, you can buy Advocate online from us at Pet Drugs online and save yourself up to 76% of the cost!

Does Advocate Kill Worms?

Yes! Not only does Advocate kill fleas and their larvae, it will also kill both mature and immature worms, such as heartworm, roundworms, hookworms and whipworm. However, Advocate does not cover tapeworms, so you will need a separate worming treatment if your cat or dog is at risk of these worms.
