Questions & Answers

10 Customer Questions

Can the dog see through it?

Answer by Chewy • Jul 10, 2021
The calming cap reduces the visual stimulus that can make a dog agitated by filtering his/her vision. Your dog will still be able to see, and can easily navigate their surroundings, however the sheer fabric reduces the amount of light / visual stimulation your dog receives, helping them to remain calmer in stressful situations.

Would like to know the country of origin (where made and manufactured) for the “calming cap”

This is exactly what my dog needs, and for the 10 seconds before she decides to rip it off her face it works great at reducing her reactivity. However, it is both extremely easy for her to get out of it and the quality is very poor, with the Velcro beginning to rip off the collar within minutes of putting it on her.

This item has been a game changer for our leash reactive dog. Careful while your pup is adjusting, ours jumped in to a shrub thinking it was a ledge. He ended up scratching his eye since he didn’t have the reflex to close his eyes thinking it was a ledge. Now that he is used to it we haven’t had any issues.

Works well with a muzzle

I cant say that its calming, but it helps that they cannot see the needle coming towards them for thier yearly shots and haertworm tests.

Dog landed up tearing it off in 5mins.. the connections between the mask and the collar connector, tore once my dog put his paw to his face to try and remove it.. He did well using it with his trainer outside the house that’s why I tried it.. and sadly didn’t work

Reasonably good coverage

It seemed to help and will use it again. We have used it twice so far for two very traumatic vet visits..

Actually works

Little bit of a learning curve but we can now take our Coonhound in the car. Before the calming cap, passing cars would drive her crazy.

Very Fast Service

I'm getting my dog used to it, to calm her in the car. A trainer put one one 2 weeks ago and it did a good job of calming her
