Dogs should be muzzled and kept on a lead in a public park Doug.
Really, have I accidentally walked into the Daily Mail comments page or something??
A muzzle is overkill in most cases if you are a responsible dog owner, AND, what you have failed to realise so far is the fact that they make a dog unable to fight back, so if you get an idiot with an unmuzzled dog who wants to attack your dog.... No, that will never end well and you will have so many legal cases/vet bills against you if you try and enforce it (not to mention the fact that you will probably be hacked to pieces in a matter of days if you go about killing people's dogs like Greg)
Also, I have never said that dogs shouldn't be on the lead..... Really, have I entered the f**king twilight zone or something?
Quite frankly, I would trust a dog over most humans any day anyway.
