The Dog Mobile Company. Bob and Angela are the loveliest people ever. I found them because some time ago there was a programme on Channel 4 I think about them, called 'Special Needs Pets' and people that had had carts made for their dogs, but they have made carts for rabbits as well, and ferrets I think. Each one is made individually to your pets measurements by Bob in his workshop, and Angela takes the orders, deals with queries, and is a bit of a comforter. Roger didn't have a cart because he was paralysed, and so it would have been no use to him, but I was determined to still keep his physio going as I called it, just to keep his heart as good as possible, instead of just leaving him to be a 'bunny of leisure'. I had a 'Quicklift' from them so that I could comfortably support Roger, and walk around the garden with him, and keeping his left side mobile. Their number is 01262 851632. They are in Bridlington, East Yorkshire.
