Durable bone that you can add a spreadable treat to
Color: Blue
Our German Shepherd was 4 months old when we purchased this. She’s going to be 6 months soon. She has been teething really bad. We wanted some way to sooth her pain. This product was just what we needed. We put it in the freezer with some peanut butter in the center on both sides. Once frozen we give to our puppy. She loves it. When we open the freezer she recognizes the ziplock package that it was delivered in which we store it in our freezer. She jumps around until we give it to her. She loves it and it keeps her occupied for a while. It is very durable. I did not notice any smell when we received it. It does not make any noise. The plastic material is safe for animals. To clean I put in the dishwasher. The only reason I did not give it 5 stars is because sometimes the peanut butter gets stuck in it and may need to go through the dishwasher twice which is not a big deal. Or you can hand wash it. I found the dishwasher was best for us. You do not even have to put anything on it, but our pup likes it. I would recommend to others.

Actually indestructible!
Style: Two pack
I am always leery of items marked indestructible because my 100+ lb. dog chews through anything I buy him. But not this. It's solid plastic that he LOVES to chew on. And I love that there are 2 of them so he can have them in alternative places to play with. The shape and texture seems to entice him and keep him occupied for a few minutes, which is a blessing!
