I need to locate a company which sells bone and/or paw shaped
decorative/novelty studs for leather craft. I think they are called
studs, they may also be referred to as "spots". Either a prong or
screw-on back is acceptable.

 The products I'm thinking of look like these
http://www.collargirl.com/studs.jpg but
something similar is acceptable. A wholesaler or retail source is fine.

A good answer will include a website or phone number of a company from
which I can buy these studs.
