What a great set of photos and you really can see how much Charlie is enjoying himself as part of a new gang. That's interesting about having been a 'swimmer' -- I have read that sometimes, those puppies don't survive at all? But that sometimes you can get them to start building up strength in their legs too. The SM could well also make him have no sensation in his paws and little ability to use them. Many human SM sufferers end up in wheelchairs with little limb function or strength. I sure hope his surgery and rehab will help address all these problems. I know Cathy already had plans for some hydrotherapy! Charlie sure ploughs ahead regardless, doesn't he? He hasn't lost any will to live.
