We just tried this product on our dog, who weighs about 15lbs. Before we put it on, we made sure to use the default factory setting, which reportedly produces a correction that would not hurt our dog. Long story short, after we put the collar on, she barked a few times and was corrected by the device, at which point she yelped, and was corrected again. This vicious cycle escalated for over a minute until I was finally able to tackle her and wrestle the device from her neck. Suffice it to say, this was very traumatic for my dog and entire family. This product may work under most circumstances, but just the possibility that someone else's dog might be tortured like ours was, compels me to write this review, which is the first review I have ever written.

I bought this hoping to avoid buying a bark collar. Our dog barks for five minutes anytime someone knocks on our door. She also barks at large trucks going by, or sometimes from a knocking sound my husband or I will accidentally make from another room. Her barking is always about what she perceives as protecting us.

Well, the only thing this "silencer" does is make her go to another room and bark instead of the room it is in. However, this will not transmit through any walls. So for it to work, we would have to buy four or five and put them in every room.

When a stranger comes to the door and actually comes in the house, she will even come in the room the "silencer" is in and bark incessantly for five minutes until she calms down. So it does nothing at all in those cases.

I wish our dog could control her barking with this, but unfortunately it didn't work for us.

Did not work at all for my dog. All dogs are different though.

Original post:  We purchased this as a preventative measure for when we picked up a new puppy. Unfortunately, when we got it, the bottle said that it was not for puppies. This should have been in the advertisement - and now it is. Don't know if will work or not, but I wouldn't have bought it if I had this knowledge.

Update:  We tried to give this to our now dog (was a puppy, but grew up).  He has not been the best traveler.  We found these in our cabinet (having bought them for him as a puppy, but not used them because they were not for puppies) and thought we would try them.  We didn't see any change from previous trips.

My dog suffers with a tremendous amount of fear whenever it is windy outside. She keeps me up all night crying and shaking. I tried this coat for her and it did not help her. I have no doubt that it may work for other dogs but just be aware that it does not work for all dogs. I had no problem returning it and getting a refund. I did have to pay shipping and handling though.

This is not working for us. Is there any trouble shooting manual? I don't understand so many great reviews and it won't work for our dogs. We are desperate HELP

We purchased an xx-large Comfy Cone for our larger dog and it worked fine.  *However*, when we purchased this "large" size Comfy Cone, our smaller dog would get it off in seconds no matter how tightly we adjusted the dog collar that was holding the Comfy Cone to the dog.  The apparent cause of the problem is that the elastic attachments that hold the Comfy Cone to the dog's collar are not spaced all the way around the edge of the Comfy Cone.  The end result is that the dog could push the Comfy Cone off her head so that it dangles from the dog collar.  If the folks at Comfy Cone would put additional attachment elastic-loops around the other side of the Comfy Cone, this problem might be resolved.  In the meantime, I would not recommend purchasing the size Large Comfy Cone until this issue is fixed.

This product didn't work at all. We have a rather small dog, he only weighs 10 lbs. He will literally eat anything and he spat this out several times. We had to coat it in peanut butter just for him to eat it. We gave it to him to try it out while we were home for a long weekend. It didn't work at all, it just made him constipated. The packaging says that the company has a 100% money back guarantee, but I can't return it through Amazon so I guess we have to go through that process now. We were really hoping that this would work because our puppy has a rough time going to the groomer becasue of the loud noises and we wanted to find something to keep him from being so anxious.

It did not work for my dog.  But I won't say its not a good product.  Sometimes things work for one dog but not another.

Nice in theory, but it didn't work for us. We have a boxer/terrier mix who is 37 lbs and very energetic. The only way we could keep this on her was to have it so tight around her muzzle that she wasn't able to open her mouth, which is not the intention. We only used it once.  However, the friend who recommended this to me swears by it!

It doesn't work on my dog. I'll not buy it again.

It is a good product, however not for our dog.  She pulls and the lease does not retract fast enough and it gets tangled in her legs.  She is a pit-bull mix and just might be too strong for the lease that I ordered

Didn't help my dog. I have a pitt-terrier whose very temid. Purchased the vest to take her on the trip, was no help. In fact, I think the vest may have made it worse, for my dog. I'M not saying it doesn't help, I'm sure it does, just not on my dog. Quality of product is nice!

This may work with other dogs, but no mine. It did not phase him at all, and anytime I used it, it gave me a terrible headache. This is one of the few products I have purchased that I do NOT recommend.

The capsules are too big and our dog will not swallow them. We tried these because our dog was not eating her food when we were using the liquid form on the food. We suspect she dislikes the fishy smell of the liquid. Our dog is a Standard Poodle.

Might work for some dogs, but not mine. I guess it depends on the dog. It's a high quality product nonetheless.
