Dogit Nylon Dog Muzzle - Comfortable Bite-Proof Anti-Bark Muzzle for Dogs, Breathable & Adjustable Design Allows Drinking & Panting - Perfect for Training, Grooming, Vet Visits & Public Outings

Bought this for Service Dog Training & its a bit big on my 50 lbs. Blk Lab Service Dog trainee but she is young & will grow into it, when I ordered it the sizing info was a tad lacking so it was a gamble. I'am sure amazon would have let me return it but the cost for it was less than what it cost me in gas to drive it to the post office & lucky for me my Grannie taught this ole boy to sew & with a few stitches its fits good as new. My opinion is this is more of a 60 to 70 pound fit range for adult dogs like Rotts.
