Very disappointed with this product. Not very sturdy. Our dog completely wrecked it the first time we put it on him. We chose to buy a metal one thinking it would be strong (we have one from YEARS ago but the straps are all broken) This one only lasted about 2 minutes. Just another example of "they don't make things like they used to."

purchased this muzzle for a female blue cattle dog. It fitted pretty well, however I had to put a couple more holes in the side straps to help fit it better, which worked, but I think the manufacturer should actually get the proper measurements of these dog to make sure they fit all blue and red heelers. The cage could be stronger. My bluey bent the first muzzle however, second time round she's adapted to it and it works. I would recommend it to other owners as it is a good product.

I purchased this muzzle for a female red heeler and it was too big for her. Maybe it has been made for male cattle dogs with the much boofier head than a female. Very disappointed it didn't fit but was very impressed as to the muzzle's quality.
