Tennis Balls, Fostoy 24 Pack Durable Tennis Practise Balls with Mesh Carrying Bag for Adults & Kids, Funny Dog Toys Playing Balls for Pets Training

They are ok with a good bounce and our dog prefers being able to squeeze the ball rather than a having a completely solid one. This means they don't last too long, but you do get plenty in the value pack.Our dog is a powerful jawed lurcher so no ball is going to last too long. They are lightweight so I use a tennis racket for dispatch

These tennis balls had an excellent bounce to them and seem very durable. Excellent value for money.

Very soft and good quality.
