I don't mind dogs and i can see how they make great pets. My wife however is both allergic and scared stiff of them so it boils my **** when they come bounding up to her if she's out running and the owners make no attempt (or a pathetic one) to restrain their dog.Dog owners, in my experience, don't understand just how much their beloved family member can affect other people. They are also uniformly surprised when their dog does something they've just spent 5 minutes telling you it never does.
I also think the status of the dog has risen so much in recent years that saying you don't like them is almost taboo. Say you don't like kids on our local Facebook group and no-one bats an eye lid but woe betide anyone who says anything against dogs or their owners.
