This is the first bite-proof muzzle I have found that has mesh over the mouth and nose that a small-to-medium size dog like my Corgi can’t bite through - plus the Velcro adjustable side pieces that come over the nose make it easy to fit it very well over the whole snout area. Most muzzles make a big deal out of their structure with the open end where the mouth is because it allows the dog to “pant, drink water and accept treats.” Since the ones I’ve tried are mostly all fabric, a Corgi with sharp teeth can still jump at someone and get a nip in that draws blood. If you have a dog that bites for whatever reason (and I’m constantly working on that with Cesar Millan’s videos) and you live in a town like Seattle - which has a “one bite rule” - if the person who was bitten reports it to Animal control your dog will be taken away and have to spend time in their shelter/dogs awaiting trial area. The dogs almost always lose the case and they have the right to put your dog down. This muzzle allows them to pant and sniff but not to drink water or eat anything. As a dog owner it’s up to you to make sure you can give them food and water with the muzzle off in your car or at home before going out. Cons: I expected this to solve the problem on walks because of the mesh over mouth and teeth and I made sure it fit correctly. After several outings he found that if he shook his head hard enough - even with it fitting snuggly - it could sail off onto the ground. Also, the center strap that goes up the center of the nose to connect with the main strap that goes behind the ears is not fixed in place so it can move around and change the snug fit. I have found this to be true on all muzzles with this type of center strap, so once I have the fit correctly established, I hand-sew the strap in place to the main piece above so it stays in the middle of the face and nose. Some muzzles prevent coming off by having a strap attached under the jaw that ends in a loop so you can slide their collar through it before buckling the collar and the muzzle. This addition would make this muzzle much more effective. We are often told to get the dog acclimated to the muzzle first and eventually they will accept wearing it. Only some days is this true for my dog. But, to keep from being sued or having him taken from me I will always have it on when around people. Only when I am unlikely to run into anyone except from a distance will I let him go without it. I always hope that with continual training it may not be necessary but I can’t count on that. My boy is a great dog and indoors he is always well-behaved, affectionate and obedient. I will not return the muzzle - in fact I ordered two more. I save the black strap material and same-size buckles from worn out muzzles and backpacks and will sew a strap with the loop on myself that the collar can slide through because the rest of the muzzle is well made and truly bite-proof. The only other bite-proof muzzles I’ve seen are the metal cage ones - which never have a good-fitting strap system or the latest ones that are shaped like a hard thick plastic duck bill that sticks out so far in front of the moth that the dog’s teeth cannot get past them. Besides being unattractive - the strap holding them on would take little for a determined dog to paw or scrape off their head against a tree or fence. The Baskerville-style muzzles do have the additional collar strap, but the opening above the nose area is just big enough for a pointy-nosed determined dog to force his teeth up through it and nip. If this vendor adds a collar strap and a way to make the center forehead strap stationary in the future, I would give it a very high rating. With Covid, more dogs are around other dogs and people than they normally would be and it’s a stressor. Much of dog biting is from fear aggression. These are all solely my opinions.My 18lb chihuahua mix is getting older and recently had to be hospitalized for pancreatitis. He's had several bouts of "garbage gut" and generally is difficult to control when it comes to picking things up outside. Basically if it's remotely edible, he'll snatch it up before you even see what it was. I knew I had to get him a muzzle to keep him safe because pancreatitis can be fatal, but I had a hard time finding a muzzle that would work to keep him from eating anything. The cage types have large holes in them and the fabric cone-shaped ones have an opening at the end. The finer mesh in this muzzle works great for this purpose. Fortunately he's surprisingly tolerant of it and not much of a chewer. He only wears it outside on short walks. I wouldn't use it longer than a few minutes at a time because it does seem to make it a little harder for him to breathe and sniff. Definitely wouldn't hold up to a chewer or an intolerant dog who might paw at it and pull it off. I also had to cut off the strap that goes up the center of the snout and between the eyes. It was useless and just got in the way. It works fine to buckle it behind his ears. I'm so thankful I found a solution that works for us, but it's definitely not for everyone.Got this for my dog, who could easily get out of it... I was hoping for something better but I got what I paid for.I don't mind it, but my dog is another question. She's still adjusting.Ordered for big dog and was disappointed in the size, but for the smaller dogs, it is fine. Not very thick. Value for money spent is okay, though.My senior dog suddenly developed the need to nip everyone. This product looks good but the reality is I think it keeps his mouth closed too much to that he has an issue breathing. It's ok for short term but I will not leave this on my dog for long periods I don't like how labored his breathing sounds. He tries to get it off and if I don't watch him he can get it off how would you like your mouth held closed by something? Sometimes the old tech is the best tech I'll probably be looking for one of the old metal or heavy rubber full face muzzles but this will do for the moment.I bought the extra large for my 113 pound German Shepherd because he was licking a wound. The fit is fine. But I have to attach this with a regular collar going through both the neck strap and the head strap in order to get it to stay on. Otherwise it slips right off, which is not a problem I’ve had with leather muzzles in the past. Other than that, I don’t mind leaving it on overnight because it does seem to be more comfortable for him than the leather. But I would not recommend it for purchase.Nice leadRobusto maniglia pratica, forse avrei aggiunto un altro moschettone per poterlo ancorare a sedie o.panchine. la mia piccola peste non è ancora riuscita a rosicchiare il cordino.Certainement anti-mastication, mais définitivement trop lourd pour moi. Mon mari l'utilise de temps en temps. Je déconseille aux personnes qui ont des problèmes de porter lourd comme moi.Bonne qualité je recommandeAssez rigide, une impression d'extrême solidité. Parfaitement adapté aux grands chiens, aux chiens puissants. Très satisfait pour l'instant de cet achat.
