Dog with Anxiety
April 27, 2020
We rescued a Yorkie Poo on Christmas eve 2018 (wasn't planned that way). Whenever we would leave the house he would tear stuff up that he could get to, ex. pens, paper. After a visit to our vet he was diagnosed with anxiety, which at that point our vet recommended this diffuser that only he could smell and it would calm him down. After trying it for the first month, it worked! However the refills at the vet was $40 for a month supply, After researching if I could get it for less, I found this site and found this same item for a 1/3 of the cost! Ordered it and it works and is the same thing I would have gotten at the vets office. I'll be ordering this every month going forward.

Merchant Response:Thanks for the review Jamie. Amazing how these pharamones are able to work wonders with anxious dogs. You and your Yorkie Poo take care
  • Helps with anxiety, humans can't smell it
  • The diffuser has to be plugged in and in an area that is open, sometimes this is hard depending on how your area is arranged

plug in warming diffuser leaks oil all over
July 15, 2019
I feel like my dogs are calmer and not as anxious over being left home alone with the oil diffuser however it leaks the oil all over. I was glad I plugged it in over the counter so the oily mess was easily cleaned up from the hard surface - I don't know what I would have done if that oil had leaked out all over my carpet. If you purchase this - be wary of plugging it into an electrical outlet that is located over your carpet or any other soft surface you wouldn't want to get all oily.
  • My dogs are somewhat calmer.
  • Leaks oil all over.
  • Won't last 30 days at the rate it's leaking.

This arrived 2 days ago and my dog is so relaxed! He has experienced separation anxiety in the past, leading to urination issues in my absence. When I left today, he was calm, and when I arrived home, there were no accidents. I immediately ordered a second unit for the bedroom!
  • This really worked for us!
  • Plug needs 4 ft clearance above

Not sure how well it works but I continue to use it since I have a dog that suffers from anxiety separation and I keep trying everything available

Excellent product

I have been purchasing this product from you directly for a few months and have used it with great success. This last time I ordered it thru Amazon (but fulfilled by you) and was disappointed that the shipping took as long as it did. I will order it directly from you only, moving forward.

Not sure about this product didn't get the results we we're hoping for. The diffuser dried out the stem on the refill and I would have to unplug it because it would burn the stem of the refill. Once the stem was wet I could plug it back in again. Maggie is still terrified.

Helpful when dogs are stressed due to weather, separation anxiety, new environment and many other reasons. Nice to have on hand to help when needed.
By Alanna
nice idea but didn't help my dog
April 25, 2013
My dog is suffering from separation anxiety....this product has not helped in the least. It is a wonderful idea but it isn't helping. I bought a refill and will use it but if the dog has not improved by the end of that one, I am unplugging the thing and saving my electricity! (Nothing I have done or purchased has helped my dog at all!!)

Vet suggested this after Clomicalm helped, but didn't stop behavior. Ordered diffuser and I didn't think much about it, but knew the month was up. I didn't get around to changing it (4 days late) -Big mistake! Anxiety came back in a big way this morning and I put the replacement in right away. Will have to see how many days it takes to bring the calm back again. Learned the hard way, this Adaptil Diffuser really helps.

Diffuser has seemed to help calm our two male beagles down. We also received the product really fast which we greatly appreciated!

DAP For The Anxious Pet
February 5, 2013
I have a lemon beagle mix and to say he is spoiled, is an understatement! I plug the DAP in when I am going to leave for a few hours and when I return, the barking ("thought you'd never get home bark") is not as harsh. They do not know that you are coming back and DAP helps. Hunter is a rescue/abused dog and DAP keeps him calm. Give DAP products a try for your pet. The diffuser refill works best for us.

This is a miracle product!
February 3, 2013
This product makes all the difference in our home. We have many rescued dogs and this diffuser with DAP keeps everyone happy and calm. If I forget to order, I can begin to see a change in the dogs demeanor and behavior within 48 hours. Would never be without this stuff!!

Review for ADAPTIL Calm Home Diffuser Refill for Dogs (48mL)
October 23, 2012
Have used one bottle already. Will have to order more in December. Our dog does become more calm during storms when using her calming device. Your price is very good.

My small cock-a-poo, anxious with thunder and loud bangs as fireworks appears more comfortable with the plug in D.A.P. My large Wienaraner, who has extreme anxiety issues is more at ease with the D.A.P. plug in and spray for kerchief around his neck.

Thanks for a good product.

I highly recommend this product

My dog Buster has struggled with anxiety of all sorts for years, since we've added the DAP diffusers and collars he's much more relaxed when we come home after he's been alone for a few hours and he's much better behaved when we meet other dogs and strangers.

have a 6 year old English Setter with severe separation anxiety, soiling inside and outside the kennel and literally hurting himself when I left. I tried Clomacalm which didn't help. I was advised to put him to sleep so as a last resort tried this and it was an instant relief! I wish I had known about this several years ago!!

I have a Keeshond (a LOT of fur). Would the collar work on her without my having to shave her neck? I would hate to have to do that, but the collar seems to be the best choice in her case.
