Absolutely fed up of having to dodge other dogs that will react negatively to mine. Today my poor dog was was inches away from being attacked by a Newfoundland, it was on leash, no muzzle and dragged it's owner over to my collie. The owner didn't even apologize. I've seen it before, it's know to be reactive and it's normally walked away from other dogs but for some bizarre reason they decided to walk it through a narrow pathway where many dogs get walked.
Every day I come across people walking reactive dogs but they never have muzzles on and some owners don't even bother to shorten their leads. Some idiots even have them off lead in the local nature reserves, which isn't so bad if my dog is off lead and can get away from them. He generally ignores them, thankfully but I'm scared one day he will get attacked.
