Yea I know they look ridiculous, I've told my DH on no account will I be pushing it, he doesn't mind doing it and if/when someone laughs I'll just pretend I'm not with him 
I just can see another solution, we're borrowing a relatives caravan for a weeks holiday and planning lots of days out, walks and picnics. Our poor old dog is 15, we walk him daily but only very short walks as he refuses to walk any further after about 15 minutes, he just won't cope with our plans.
We can't leave him in the caravan on his own and It seems a shame to put him in kennels when he could come with us as he loves the car. I'm thinking he could walk till he was tired then we can push him in the buggy for a bit till he wants to walk again but would it be a total waste of money (we're not rich).
Has anyone got a dog buggy and do you use it?
