BASKERVILLE Ultra Dog Muzzle- Black Size 4, Perfect for Medium Dogs, Prevents Chewing and Biting, Basket allows Panting and Drinking-Comfortable, Humane, Adjustable, Lightweight, Durable

I got a size 4 for my 45 pound dog, and it is a bit big (kinda goes in her eyes). But it works perfectly. She has enough room to pant and lick. It is adjustable so that’s good too. It is really good quality, good muzzle & buckle to secure. It is pretty easy to get on and off, just securing the buckle. My dog doesn’t mind it, when we put it on her I put some food pebbles in my hand behind the nose of the muzzle, then once she puts her nose it it, I snap it on and she is able and to get the food pebbles. It has enough of an opening where I can feed her a little, but not big enough for her to snap or cause harm.

This is a great product. I really like the fit and gives my dog the ability to breathe.

Looks like good quality, just make sure you pay attention to the size when ordering, they seem to run big.

The size recommendations are way off. The circumference standards aren't close to my dog's and completely unhelpful. The eye-to-nose measurement is informative, but still not determinative. It would have led me to purchase a model larger than appropriate. My dog, a Boxer mix, is supposedly a size 5, but I read enough reviews to order a 4 and it fits perfectly --neither too constricting nor too loose. With that minor reservation, this is an incredibly well-designed product. The reviewer who says he regarded it as only an interim solution while awaiting a much more expensive rigid steel basket is nuts. The virtue of this product is that it secures the dog's muzzle without impairing the dog's vision, movement, and comfort as a metal muzzle would. The rubber material is not heavy enough to be annoying while still providing the desired stability. My dog adapted to it immediately. He now voluntarily puts his head into it. A few times he has rubbed his head against grass, but I interpreted that to be more an effort to relieve an itch than to dislodge the muzzle. He has never used his leg, for example, to try to remove it as dogs often do with medical cones. I also don't get the gripes about closing and locking the ends of the muzzle. That feature is similar to that found on my dog's collar. The key is to lift the female end off the male end rather than trying to force the male end out of the female end. As long as you apply the two pressure levers at the same time to the same degree, the female end lifts off easily. Nor do you need a second collar to secure the muzzle; its securing loop easily slips on and off the dog's existing collar. I was self-conscious about resorting to a muzzle because I thought it indicated some inadequacy in my own ability to train my dog or my dog's character. I was wrong about that. In many cases, we don't, and cannot, know what triggers each individual dog to express his anxiety by sometimes biting. All we can do is contain that instinctive reaction he can't control himself. I am so grateful to have a device as carefully conceived as this one to do so.

My one-year-old dog, a black lab/greyhound mix, eats rocks. Lots of rocks. And after an expensive surgery to alleviate the latest mineral meal, we knew it was time to try something different, before she killed herself or our bank account. We purchased this muzzle, along with a plastic "Basket Cage Dog Muzzle", hoping one of the two might work.The generic one was a bust--the strap mechanism was awful, simply sliding off, and construction was cheap. We dumped it within a day.This, on the other hand, has much more possibility. The rubber is flexible yet tough, much more reliable than the first one. And it feels like it would be more comfortable (although, of course, she hates it--who wouldn't, except perhaps Hannibal Lector?). Now, on the downside, she's already broken on of the ribs/spokes/bars of the cage, not in a way that helps her eat rocks, but we've only had it for three weeks, so I'll admit I'm concerned about its longevity.The straps, too, are rugged, but they also present the biggest issue. It's a belt-like design, with a tongue that slips through holes. And the holes are hidden in a strange fold-like construction of the strap. So every time you're starting out from ground zero, with different tightness, sliding the strap back and forth, hoping to catch a hole on the tongue. Which doesn't sound like a big deal, until you remember ... it's a dog. And dogs aren't that patient, particularly when they want to go outside. My children get so frustrated with the issue they often "forget" to put the muzzle on, and my wife complains about it as well. I keep telling them, "with use, I'm sure the holes will open up," but so far, they really haven't. An alternative construction, with one of those snapping clasps on the same rugged strap, would make all the difference in the world.There is an additional strap, which runs over the dog's head between the eyes and attaches to the main strap. A good idea for stability and snugness, but the design of the clasp doesn't actually fit well on the main strap itself, and it's constantly coming off, leaving that strap to swing and bap our dog in the face.Now, the final element--besides rocks, she also eats poop. Yes, I know. Ech. And since she's worn the muzzle ... we've still witnessed her eat poop, through the holes. The holes in this muzzle are much larger than those in the cheap "basket" one referenced above, and they allow entry of much more than water. So, is she still eating rocks? We haven't seen her do it yet, poop's a bit more malleable, but I'm not guaranteed she hasn't.So I give it a three, probably would choose three and a half if available, based on our limited experiences, but even with the promotion of this muzzle as a breakthrough device, I think there's great room for improvement in this particular product area.
