My Doberman loves these! That said, she doe's tear them up over time because once she gets one, she squeak's it continually and chews it. They are tennis ball which are not made to withstand aggressive chewers, but she loves them. They are a great size for her, we play with them every night. She's not a picker and doesn't swallow things so I let her have each one until it's destroyed. Then we get out another one to start the process again. They are a reasonable price for the fun she has.
