Don't say 'just don't do it' please! I've been running with him for years but the lead seems to whack the side of his head (he's a fox terrier so is small); in a harness he will slow; he is forever stopping suddenly to pee & he drives me nuts.
I don't run fast any more as I now have chronic knee problems (wear n tear due to age) so now I just want to jog gently round the block with him. He trots quickly if I walk with him so I might as well jog.
How do I make the experience more comfortable for him?
