I made a quick tag idea from the Cuneiform Alphabet that Copper posted, it's just FB for Fido/Bino but I thought they fit well together if you put them vertical. Also it fits in with what Mickey said, it's closer to his body shape and style:
Also, artistic comments:
I like the elbow and knee patches, it's different and unique to the other Housepets, but I know some people don't like them and I'm not going to cry if they're removed.
I liked the design on the old tail but I also like the tail he's got now. However, I would definitely like to see an interesting fur pattern on him somewhere. Maybe even a Rorschach type design that's constantly changing but in subtle ways.
I like the solid gold collar but I don't think it should be overly
gold if that makes any sense. Like, a little duller so you'd have to get close enough to find out whether it's real gold, then since no-one's ever been that close to Fino, it'll remain a mystery...
Also, whoever does the colour pattern for Fino will have to take into account the colour of his collar and tag. Just to make sure everything goes.
EDIT: Just thought of another tag from the Cuneiform alphabet: AZ as in the Alpha and Omega, which, considering he's from the same litter as Bino, Fido and Joey and yet was around when the Cuneiform Alphabet was being used, I think it's appropriate:
