I am very impressed with the quality of the product. My 6 year old American Bulldog wears a muzzle with joy. I introduced him to the muzzle using peanut butter, spread a small amount on the front and he immediately wanted to put it on. However, when I take him for a walk, he walks a little funny and sometimes touches the muzzle with his paw, but when I praise him very much, he forgets about it.
