Greyhounds love their toys like rubber squeakies, stuffed animals and rawhide chews. Pick them up at garage sales or pet stores, but first cut off the eyes, noses, bows or anything that can be easily swallowed. When it comes to treats, hard dog cookies are just fine. Good quality dog chews should be a decent size so the dog has time to chew away. GAC recommends only products made in the United States.
