A tennis ball is a soft rubber ball covered in cloth. Tennis balls make great toys for fetch and other interactive games you can play with your dog. Take care to choose a tennis ball that is the proper size for your dog. The ball should not be able to fit completely into the dog's mouth. For medium to large dogs, the regular tennis ball you can buy at the local mart is perfect.
The tennis ball is a great, versatile toy that is inexpensive. Once tennis balls are broken are your dog starts to chew them, discard them immediately. Never let a dog chew a tennis ball. Tennis balls should be used for game time, then put away where the dog cannot get to it.
