HEAVY Brass Or Bronze Metal PLAYFUL DOG Bookends - BUTT UP - Hound dog, spaniel?

This listing is for a pair of HEAVY Brass Or Bronze Metal PLAYFUL DOG Bookends - BUTT UP - Hound dog, spaniel? Condition is used. These are from a estate. See photos for best overall description of condition. I don’t know if these are brass or bronze no marking I could see anywhere. They look like hound dogs but I’m not sure they could be some type of spaniel or other breed. These slide easily because they are all metal. Buyer should consider placing rubber or some type of felt to them to keep them from sliding.
