5 dog bone/biscuit ornaments

Vintage 5 never used dog bone/biscuit ornaments. There are 3 "Milk Bone" ornaments in 3 different colors brick red, brown and green. I think they are ceramic. Measure approximately 3.25" x 1.75" x .75". The other two are hand made by an artist who signed them on the back (but I can't read) of stone. They each have a colorful plaid ribbon wrapped around them. Measure approximately 3.5" x 1.5"x .25". All are in excellent condition with no flaws.
