I bought this because my dog eats dead fish on the beach. She has good recall but once she finds a dead fish it becomes a game of keep away and ruins our whole day, and possibly the next several days if she gets sick.

This works. Perhaps not perfectly but my expectations are not perfection. I expected a lot of resistance and discomfort, but she actually didn't seem too bothered by it. I put the muzzle on, gave some treats and let her run. Sure enough, she found a dead fish. Pre-muzzle, she would have had the fish in her mouth and been a complete a**hole until it was gone. I was able to get to her before she could get the fish in her mouth (she would have been able to with more time), get her away from it and give her some treats. This has happened a few times, and she also found an injured bird on the beach and this muzzle probably saved the bird's life (I took it to a rescue). I think this is going to help me train recall too, because she's learning that she's not going to get the fish before I get her, so maybe the treat I'm offering is a better bet.

Overall, a mesh muzzle is great if you have a dog that eats gross stuff. Now that I know it works, I'll invest in a better one. This is a cheap option that you can get fast, which is what I needed because we were at the beach and I needed it ASAP. Better ones take weeks to ship, but I will be ordering something that's higher quality.

As far as fit, the band that goes across the top is really close to my dog's eyes, so I have it fitted really loose. I probably would have gone a size down to allow for a looser adjustment to avoid the band interfering with vision or comfort. It's pretty adjustable so don't stress too much about sizing and if you're undecided, I'd say go with the smaller size. Importantly, my review is based on preventing eating dead stuff, not biting or aggression. A tighter fit would be needed to prevent biting.

We have a dog who eats EVERYTHING so she has to be muzzled most of the time. I have bought this muzzle twice and another one. I like this one better as it does stay put well. She had figured out how to pull it down a little bit to get stuff off the floor but it's the best I have found so far.

I really really like this muzzle. I have two chihuahua-wiener dog mixes so they needed an XS though one of them could get away with an XXS (his snout measure is in between both ranges) but I am always a little weary when it comes to sizing. I love my chiweenies but they aren't the most social and can be down right jerks to outsiders. So one has a biting problem and the other won't stop trying to eat garbage, this muzzle has been a godsend, stopping both of them. Though if you're hoping to deter poop eaters this probably won't help much since mine are very happy to cover their muzzle in mud, don't want to consider if they were poop eaters.

They both adapted to wearing it fairly well, they're not too fond of it but they will stop taking it off. I really only use it during walks so they get used to it long enough for them to enjoy them. They will give sad eyes and sulk on the ground for a bit because they love chewing on anything they find but no whining.

I will say it's not too durable/sturdy. During the first week or so my boys did start to wear out the fabric. Kinda expected since they did resist it and tried rubbing against anything they could but they've gotten better. One even tried to bite/pull it off the other, didn't get it off. Thankfully it didn't ruin the general structural integrity. The biggest issue I had was the buckle. Sometimes it'd get stuck for no reason (I had collars and harnesses with similar buckles so I know how to fix it), up until recently it was only when I buckled it for storage. Today it got stuck while on my dog and rebuckling/positioning it didn't work and we had to force it off. It cracked unfortunately. I've sent an email to the seller. We'll see if I can get a replacement. EDIT: customer service was quick to respond, very helpful and offered to send a replacement

My dog eats a lot of grass whenever we go walking, so I have to use a muffler. He didn't like the others I have tried but he does not mind this one. It is surprisingly secure. It doesn't come off when he shakes his head. Easy to put on. I highly recommend it!

It doesn't hurt my dog when I put it on him to cut his nails. Plus he actually wags his tail and slips his face right in it.
I do however hold on to it the whole time not 100% feeling safe that he can't slip right it and bite me.
