You can't wrap them up in cotton wool Rob,no its not ideal for dogs especially for Whippets but hey ho sometimes you have to make the best of the job at hand with the tools you have IMO?
very true mate, I used to pick and choose my runs with last dog, at first, then I just let her get on with it.. and out of all the places she could of died, it was in the field right out side my house where she new very very well, lost her foot on a little rock sticking out ground and tripped and snapped her neck....
I know what you're saying, and I've heard a few stories about dogs killing themselves
