Going back to the dogs , all of my three examples have hollow blown bodies and solid heads. Crimped front paws ,nostrils, rough looking collar , and are all clear cased. Plus the curling tail. I think Chris's dog might have a solid body.
There is one correction I need to make and that is the eyes are made from cut canes (I can see through the head

) . The canes have a black core and a white surround.
As I said above the dog and the first green boat above, were bought from a lady who lives in Malta and she bought them at the time they were made.
