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.

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!

Fast service!!

Very quick turnaround on quality products

Worth every dollar

I have 4 100lb plus dogs, 1 small dog and a cat. I only use activyl for my animals because it works better then anything I have ever tried and it's cheaper then most flea treatments you get at the store. 5 stars for this product and i recommend it to everyone i know who has animals.

Activyl AND Countryside Pet Supply are Still the Best at What They Do

After trying SO MANY other flea treatments -- both OTC and prescription topicals -- it seems to me that Activyl is still the most effective when it comes to killing fleas here in south Florida.

On a separate note:
In these challenging times of broken supply chains, I made the initial mistake of ordering this purchase from a different online site because they were offering a 15% discount.

Like I said: What a mistake.

On this other retailer's site, they stated that I'd be receiving my order in 8 to 10 (presumably business) days. Long story short: After two weeks of my order still "pending" (they had no problem taking my payment, however) and never getting a response to my inquiry from customer service, I asked my bank to dispute the charge (which was eventually credited back to my account).

I then decided to call CPS, since they have always exceeded my expectations in every regard.

Just like before, I spoke with a very pleasant CSR, who assured me that they were not experiencing any shipping delays due to the pandemic, but since the warehouse had already closed (it was late afternoon), my item wouldn't be shipped until "tomorrow."

True to their word, I received an email the very next day confirming: 1. That it had been shipped; 2. When to expect the item; 3. Link to track the package.

Although the estimated delivery date was already incredibly acceptable, it even arrived two days ahead of schedule!

I can't thank these personable family members and their always reliable service enough. I also won't be wasting my time with other online pet suppliers in the future because the simple truth is that CPS prices are already low.

Thank you for being there for our beloved animal companions, CPS. You are not only "essential," but unrivaled as well.
