Can I join the dog scar club? I was bitten on the thigh by an alsation. The owner said it was because I was carrying my hat in my hand. Obviously my fault then. I wish I'd reported it, but I had no way of taking down details, and was miles from home.
That encouraged me to buy a dog dazer, which I've only had to use once in anger, but it worked a treat. The Jack Russell that was going for my ankles leapt backwards with all feet off the ground and an alarmed expression on its face. The owner was none the wiser and I carried on running.
There is a good review here (in a peer reviewed journal) suggesting that the "wear and tear" caused be exercise is not an important factor in osteo-arthritis:
Horses can be lovely I'm sure (ask the French), but they shouldn't be on footpaths, and owners should be forced to clear up the crap they leave behind.
