Got my pup's toy today and was super excited about it. I got the green and I love the color, texture, durability of this toy and I love that it's innovative. It came boxed very nicely and will all the parts and was charged and ready for use. I didn't understand the tail part until it started going and I really like that it flips to roll the other way or spins. So far, my dog is enjoying it. I am watching to be sure he's not biting it as a teether, but overall I feel like it's good money spent for a great purpose.Update 8.23.2021. Received the bone on 8.1st and he loved it, however as of this weekend, some 15-20 days later, it only spins on one side, thus only making a circle. Have tried doing a full re-charge and "nothing" / same results. His interest is Zero now & my frustration level is @ 100. I see this same issue w/ other buyers, so can someone offer help to fix this. This was quite an investment for a dog's toy and I'd like it to work properly.. so I can get my money's worth. HELP!!!!
