I've had dogs all my life. Love them. All of them would wear a muzzle if required - for example when travelling on a ferry, or we had a couple of garbage raiders who had to wear them on walks to stop them eating rubbish. We used the basket type ones, so no breathing issues.
It wasn't an issue. We put the muzzles on, the dogs looked slightly baffled but forgot about it. No issues.
Why are XL bully owners making out it will be so hard to muzzle their dogs in public?
