Query: Great Price. Long Lasting. All Natural.

My pups seem to really enjoy these, and I enjoyed the price and convenience of ordering via mail. Good for smaller dogs. Larger dogs may choke on them.Long lasting. Kept my pups busy for hours. No dyes to soil carpet. Not a messy dog chew. Good for their teeth and digestive systems. All natural.
