Guardians Dog Muzzle,Dog Mouth Cover Adjustable Nylon Strap Anti Bite Pet Muzzle Dogs Training Safety Covers(007#, Large)

Seems to work OK but I think the sizes run a little large. I also had to add an additional shoestring harness because my Australian Shepherd figured out how to get it off pretty quickly.

I have a German Shepherd, measured exactly as instructions stated. The muzzle didnt fit, too large. I tried to return only to find out they want to charge $6.04 for return shipping. REALLY?? The plastic is so hard even if I did use it I would have to add something to keep it from causing rub injury to my dog. This is very cheap abrasive plastic. Not worth the money, time or effort. What a waste. I wont even donate it, its not good enough quality.

These are stiff and don’t seem comfortable or effective. She can get it off her head easily. I wouldn’t really recommend these.

This works well for my dog, she can drink, bark, pant, breath, but once she learned how to get things through the "bars" under her chin, she broke them so I have to put something around the 2 plastic "bars" to keep her from breaking them. I also need to put a stitch in the strap to keep it from getting loose enough to remove. I have to buy a new one every 6 months or so, but, this is the best option I can find to prevent her from eating things that are not good for her.

These must have been around a while I see these exact ones on dogs being rescued all over the world. So ya there proven and work great for my lil dog when I trim his nails little bugger will bite me if so I got this muzzle:).

So far, so good. Not very good quality but if other dog does not get ahold of it, it might last a little while.

this was perfect for what I needed it for. The ONLY thing was that the size chart might have been misleading OR I got the wrong size. It was just a little big but it was also WAY to big on the part that clipped around the back of the neck. So I have to do a little cutting and relooping through the buckle. keeps him from chewing on his kennel and hurting his snout.

Useless. We have a Wheaton terrier pup who developed a taste for our plants. Not a viscous pittbull. He shredded that muzzle in 4 hours he was left home alone. Ironic considering it was supposed keep him from chewing staff. Also the strap is way too big and not really adjustable. We had to cut it and melt it back together (synthetic fibers) to size it properly. Going for the real metal and leather belted muzzle this time.
