Product Description

Activyl for Dogs

What our customers say

"Great treatment for fleas"

"Activyl for dogs is the best flea treatment I have ever used. We have two dogs and Activyl keeps them flea free. It is a wonderful product. It is the most effective product on the market I have ever bought."

                 Linda B.

Activyl is a highly effective spot-on flea control treatment featuring indoxacarb and a mode of action that uses enzymes inside the flea to activate the serious flea-killing power.

Activyl really gets rid of fleas!

Both pets and people want a flea treatment that's really effective at killing fleas and preventing infestation, but how it works matters, especially regarding the impact on your pet and home. Ensure that your furry family member gets the best care possible. It's also quick-drying, fragrance-free, waterproof, and remains effective even after bathing.

Activyl breaks the flea life cycle

Unlike some flea treatments,  Breaking the flea life cycle is important, so your pet is not re-infested by new fleas developing from flea eggs and larvae in your own home environment.

Activyl for Dogs is the flea treatment just for dogs and Activyl for Cats is the flea treatment just for cats.
Both products kill adult fleas and also break the flea life cycle, so you're much more likely to solve your pet's problem for good.

Step 1: Application

Activyl spreads through your pet's skin and coat.

Step 2: Contact and Ingestion

When a flea lands, it takes up Activyl (no bite required).

Step 3: Activation

Enzymes inside the flea change Activyl into its fully active form.

Step 4: Flea-Free

The flea is soon unable to feed, becomes paralyzed and dies.

NOTE: At the beginning of Phase 4, fleas become disoriented and move in the coat of your pet, which makes them more visible to you. These fleas stop feeding, followed closely by paralysis and death.

Please bring this product back

I see the manufacturer has quit making this. It was the only thing my vet recommended that was compatible with the Seresto tick collar. Bummer

The only topical that works in Florida

Fleas are aggressive here and reproduce year round. This is the only topical that works and is the safest anti fleas product for our pets, on the market, because it doesn’t load into their bloodstream and it doesn’t damage their internal organs like the anti fleas pills do. I don’t know what the politics are behind discontinuing this product. It needs to go back on the market. We love our pets and their health is important to us.

I never gave my pups Comfortis, Simparica, Nextguard, Bravecto or any other pills, because they cause so much damage. We struggled with Advantage, Revolution, Frontline. They don’t work. A friend told me about Activyl, and boom! No more scratching!!!! I put a sweater on my pups until it dried on the skin, so they won’t accidentally get it on their paws and lick it. Finally something on the safer side that works against the aggressive fleas in Florida!


As I already mentioned in previous survey, I'm very pleased with
your company's quick service and shipping.


Xlnt service, easy order, super fast shipping. Love this place for my pets needs

5 Stars for Activyl for Dogs

Activyl for Dogs is the best product that I've found for fleas. All other brands including Frontline Plus have developed a resistance for our fleas. I was so happy to find a product that has worked consistently for my dogs. The price is reasonable and Countryside Pet Supply ships quickly with the lowest price that I've found!
