I had to smile when reading the dogs for rehoming page, at the number of dogs who are described as 'strong on the lead' - no, Bessie sweetheart, it's not just you! What you need is a masseur/se to keep the walkers happy - any volunteers?
I also smiled to see Jimmy on the rehoming page:
JIMMY is a fun loving very friendly black boy. He has a very nice nature and loves everybody. He is a very easy dog to walk on a lead and will make a great pet for some lucky person. He is no problem with the other dogs.
He sounds like the perfect greyhound - it that why he got the name?

He probably was named that to prove all Jimmys ain't old and grumpy like me Marion.
