W have been searching for something "chewable" for Toby that is SAFE. He needs something to help occupy his time for short periods at a time, he is always supervised, never left unattended with anything. He can't have antlers or bully sticks. We have tried the himalyan chews, but can't have those, either. We have had 2 pet stores highly recommend these wood chews. Both stores told us these are completely safe, safer than nylabones, which we also don't give Toby. They said as they chew on them and get wet they get softer and can not splinter. Hmmm, I don't know if this is a good idea to use these. We have been freezing kongs with plain yogurt and banana mixed in. He loves that, but is getting bored with it. Since his surgery he is bored out of his mind and we need something for him to chew on. He is a super power chewer so we don't want anything he can break a tooth on or swallow pieces. We also have the green everlasting ball which we put pieces of treats in but he is also becoming bored with that. Any thoughts or suggestions?
