Four PawsmQuick-Fit Dog Muzzle

For the price, I am very satisfied with this product. This product fits my boxer very well, which is hard to find for their short snouts. His snout was exactly 10 1/2" as is recommended for this product. He has not been able to get it off, although he has not tried very hard to get it off yet. If you get this for your dog, I would recommend that you view and follow the training tips on the video on youtube called "conditioning your dog to wear a muzzle." This method works well for teaching dogs to wear any type of muzzle. I bought this muzzle because my dog has a nervous aggression around people and other dogs. I have not tested it out with other dogs yet, but it has worked well at preventing him from nipping at people. To my suprise, it has actually calmed him down around new people. We have been doing training with him to expose him to more people, but he has still been very nervous and has occassionally nipped at our helpers. After using the muzzle to train him we were still able to let our guests give him small treats for his training, and without the fear that he would bite them. He has not even attempted to bite at our guests since we got the muzzle. Another advantage is that he is not able to bark very loudly when they come over when he is wearing this. The only thing I was initially worried about with the muzzle was the seams on the inside of the muzzle. I was afraid that it would rub on my dogs snout and rub it raw. Thus far it has not, but the longest that we have left the muzzle on him is about twenty minutes. I would not recommend leaving this product on long term as it does not allow the dog to open his mouth wide enough to pant very well. But he is able to drink and eat small treats with it on. Overall, I would recommend this product to someone if they are using it to restrain their dog from biting or barking for short amounts of time. For a dog that needs to wear it for longer amounts of time or will need to pant to keep cool, I would recommend looking into getting a basket muzzle that will allow the dog to pant more freely. Update: I've had this product for a while now (2-3 years?). It is holding up great! There are no tears or problems with it at all. I have noticed, especially when it is warm outside, it tends to get quite itchy on my dog. He will rub his face on the ground to try to itch under the muzzle and it does cause some redness around his snout from rubbing his face on the ground. Overall, I am still very happy with this purchase and it has brought a lot of peace of mind to us with our dog who still occasionally needs to wear his muzzle. Since Amazon won't let me enter a webpage link, try searching "Four Paws Quick Fit Muzzle Sizing Chart" in a search engine. The first link pulled up a sizing chart on the fourpaws website. Make sure to measure around your dogs snout at the widest area up by its eyes.
