  • ADAPTIL is vet recommended.

Why did the price double for this item?

What does it smell like? A pleasing scent would be an added bonus!
Answer by ChewyDec 21, 2017
The special scent (odourless to people and other animals) that Adaptil utilises is a replication of the pheromone that mother dogs naturally emit to their puppies just after birth, to comfort them and reinforce the attachment between the mother and her offspring.

I have an air purifier in the room I'd like to use Adaptil in. Will the air purifier clear the air of the Adaptil scent for dogs? Should I turn the air purifier off when using Adaptil?
Answer by ChewyApr 30, 2019
Adaptil diffusers may be used in the same environment as an air cleaner. If an activated charcoal filter is used, the filter may retain some of the Adaptil molecules. However, this should not lead to a decrease in efficacy as Adaptil is continuously dispersed while the diffuser is in use. To ensure best results and diffusion throughout the area, it is recommended to place the diffuser away from the air cleaner system (approximately 10 feet or so).

Is it okay to use this in a room that also houses cats?
Answer by ChewyOct 25, 2017
The pheromone will not affect the cat so you can definitely use this in your home.

Husky does better

My husky does not lick his back paws like he used to. His back paws are almost completely white again with the aid of the diffuser next to his kennel and the adaptil collar. The vet suggested this to me when I took him in for his annual checkup and saw his back paws, the fur had turned a pinkish brownish gray. It was horrible looking, both back paws looked like that and were always wet. Between the diffuser and his adaptil collar, his paws are almost white again. I'm a happy husky momma again :-)

One of our beautiful white German Shepherds slipped her collar, ran out into the street & was hit by a car. The damage was so involved the she had to be put down. Her brother went into a deep depression, moping around the house looking for his sister. This Adaptil has really helped put him back to his regular healthy, bouncy self. I would highly recommend this product!

Trainer recommended

Got this upon the recommendation of our behavior therapy dog trainer. Seems to be helping. Mr Tobey is a bit more calm at home.

We used this product for 5 months and unfortunately it didn't have any affect on our nervous Australian Shepherd and Australian Cattle Dog mix. I believe it works for some dogs, but not mine.

Nice product

This will take a while to help your dog. I missed that the defuser was empty after the first month. This was right before 4th of July, that was a mistake. The dog needs to be on this all the time but it does work. I use a Thunder shirt and melatonin with the defusser.

Maddie love her diffuser

Maddie chooses to sleep right under the Adaptil diffuser even though it is a few feet from her bed! I am considering the collar to take on the road. I have used the spray for my cat and in the car when we travel, too
