These are not suitable for medium to large breed pups that are teething.

Like all tennis balls pups enjoy pulling off the furry coating but the squeaker inside is too attractive for pups and they enjoy trying to remove it with our pup removing two squeakers. These tennis balls need supervision in medium/large breed pups. Best to use together and take away from your pup once played with. We had a bad experience with our pup when she ate half a tennis ball and the squeaker. Fortunately the outcome was good.

My Australian Cattle Dog loves anything that squeaks and these balls are a great buy. Eventually the ball will lose its squeak but it far exceeded my expectations and for the price can easily be replaced time and time again.
