Hi Rose,
Thank you for your comment. I have looked through all of the various murano designs for dogs and can't find any the same, and I also can't find any similar one colour shapes.
I only mentioned whitefriars as it came from a collection of this dog plus six other pieces of whitefriars glass. There was no murano or other makes of glass in the collection?
I know it is very unlikely to be whitefriars as they didn't make dogs, but I do really admire the quality and charm of this piece, and I am not usually a big admirer of the murano glass dogs similar to the one you posted in your link.
Hopefully someone will recognise the maker or style, or have a similar example, so I can find out more about them.
Best wishes, Michelle.
