My golden retriever puppy would sell her soul for a tennis ball. It's the most adorable thing when she has a few of them and is trying to put them all in her mouth at the same time, or pawing at one while chewing on another. We love getting the tennis ball club subscription because it keeps things fun and exciting for all of us. She loses balls or they get filthy so it's nice to know we'll never run out. The balls are also great quality and she isn't able to chew the fuzz off as easily as with some other big name brand tennis balls for dogs. They bounce great and the squeaker is just an added bonus. Kyra Approved!
