He looks like a Fox Terrier to me Rose and you said he has a lot of aventurine in him, so how about the Italian for Golden Puppy, Cucciolo d'oro. and you could shorten it to 'Cuchi' as the Cucciolo is pronounced Cuchiolo?
I have a lovely big striped Barbini duck with a golden beak. I bought him on Feb 14th, so he is called Valentino Oro-becco-Pijiama!! Pijiama was because his stripes made him look as though he was still in his pyjamas!!
He is lovely and certainly deserves time taken to find the right name for him.
