Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Perfect for Blind Dogs, Fun and Durable
Size: 2-pack, Style: Duo
My blind dog loves these Chuckit! sniff balls. She can easily sniff them out and plays fetch with them for 20 minutes a day, even running up and down the stairs. The balls are durable, bounce well, and the bacon and peanut butter scent keeps her engaged. I do wish Chuckit! would bring back the version with a tone so we could play fetch outside more easily. Overall, a fantastic toy for dogs that rely on scent and a fun way to keep them active.

My Golden Loves
Size: 2-pack, Style: Duo
My 8 month old Golden Retriever loves these. It is also one of the few products she cannot destroy. They smell as described and she loves to chew them and play fetch when. She can chew these easily without destroying them. Overall good value for the money for my Golden
