One thing though, is what do you do re dog poo. I know most people do the plastic bag thing eeew ( I supposed I will have to get used to that) when out running shurley you can't carry a bag of stinky poo around with youuntill you find a dog poo bin......
You can, and you'll even find that in the depths of a cold winter it can be quite a godsend !
I've got two Northern Idiots ... I used to run with the eldest all the time, but found the longer distances on roads started to play havoc with her paws, and the bootie thing is just NOT an option, so stopped taking her for a while. She will still occasionally come out for a 4 / 5 miler on the road but I limit them to prevent re-occurences of the paw thing. Echo the youngest will also occasionalyl come out for 4 / 5 on the road but again I try and limit those too.
When running on the road they are quite happy on the normal lead just to trot alongside, and soon learn the requisite pace.
I have now started venturing on to the trail side of things so when I go out in to the fields they both come and will happily run off lead for 5 / 6 miles with no issue (only problem being for first mile they think its a game and continually try to take me out!)
I'm hoping to start extending the distance of my off road runs, so will take them out on those too.
Emmy, I think crampons may be the order of the day .... although in all seriousness I'm going to be wearing my road shoes (mainly cos they are the only ones I have and don't think have time to get trial ones and break them in to 26.2 distance!).
