Kumfi Dog Safety Muzzle Size: Medium - humane and comfortable calmer

Good - not been able to get it off. Not stopped all the barking, but an improvement, which I am hoping will improve.

Firstly, Amazon managed to send two and charge for two even though I ordered one. Then the sizing is off. I have a cocker spaniel and similar size dogs say to buy a medium but even at the tightest setting it slips off easily.

Very good fit without causing the dog too much discomfort. Does the job well

Had an empty box delivered, very unhappy,
