He is handsome alright! So when I look at the pics what I immediately think of is he is just underweight ....which is a fun thing to fix
I have attached a pic here of my old man Humphry....I attach it for comparison as Humphry appears to be similar in size to Frank....when Humphry came into my care he was underweight and his front legs/neck area was thin like Franks....
So, my suggestion would be to get him big piles of dandelions...rose petals and other stuff you have noticed he love and let him eat until he can't eat anymore...then give him a grand ole soak after
