3 Packs Calming Collar for Dogs, Anxiety Relief Pheromone Calming Collars Up to 60 Days Efficient Relieve Stress&Relax for Small Medium Large Dog Comfortable Collar Breakaway Design Gray 25 Inches

I could see improvement. The smell is overwhelming.

Purchased these collars for helping our new puppy adjust to his surroundings. I didn't have high expectations for it but honestly I think it does help. He seems calmer and more easy going once the collar is on. It didn't bother him. He doesn't try to chew it or anything. It smells good so it helps with dog odor as well. I am only giving it 4 starts because it says it lasts up to 60 days per collar. While "up to" is technically true, we change them in about 40 days. But with 3 in the box we are still getting over 3 month's worth of use out of them.

This works better than anything we've used! It calms my dog down during rainy weather. My dog only weighs 4 1/2 lbs. and I wondered if the collar would be too thick, but it's not! I just trimmed off the excess length that would have been used for a larger dog. It has a nice smell but when you first take it out of the packet, the smell will be quite strong. Just leave the collar out of the package for several hours and the strong smell will significantly decrease. I would recommend this for any dog that does not handle storms very well.

The collar was a nice size I needed it for two dogs one large and one small and it suitable for both. The smell was nice and not overpowering, neither dog itched or seemed to be bothered by the collar or the aroma. I have and American bulldog and a pug the bulldog has separation anxiety and was destroying crates. We purchased a new crate and since about a week after the collar was put one, she hasn't vomited in her crate and still has the tray with minimal chewing which doesn't seem like much but when she was chewing the entire tray and vomiting it a big improvement!

I initially purchased this product to help calm my ever so energized Shi tzu puppy. She is very lovable, but loves to nip, jump and play ALL of the time! Well, the collar has not curbed her wild puppy behavior, but the collar gives off a wonderful aroma that keeps puppy smelling fresh! So, for the amazing scent alone, I recommend this product. Its been almost 30 days since my purchase, and the beautiful scent still persists.Great!

We have 3 pups. 2 are a bit over the top. These have made everything so much better from the house sitter when we were out of town to walks and general things that freak them out.

And I can't handle it gives me a bad headache and my pup dont care for it either.

It definitely calmed him but he was still shaking during big thunderstorms. Is there a stronger version? It helped my friends dog who gets scared in the car. Great idea!

Bought it for my then 5 month old labrador puppyShe has separation anxiety when I leave. Unfortunately the product did not work for her

It seems to work but without being able to converse with puppy about it. Lol

They didn’t work to calm our dogs much although they do smell quite nice.

Didn’t work for my dog.

These collars were way too small. I though about putting them on their front legs but that would be silly. One thing is to measure your Fur Baby's neck!!!
