Dog balls are a very entertaining toy for dogs - they can be chewed or fetched, depending on you or your dog's mood.
Like just about anything nowadays, there is a large variety of dog balls that you can find in pet shops, or in online stores - if pet shop feels a little too far away. Animal shelters are also a great place to learn about and acquire dog toys: if you decide to adopt your dog from a shelter, the employees may already have a list of his favorite activities and toys. Like children's toys, balls for dogs are now customized - they can have certain colours or drawings on them, they can make noises when squeezed, they can take different shapes and sizes. You can basically choose dog balls to suit your tastes but also your family's or your dog's preferances (if you have such information).
Advantages
The main advantage is keeping your dog in shape and entertained at the same time. It is a good idea to encourage the fun, lively side of a dog's personality and playful games are the best way to do that. Exercise will keep the dog fit and his health will be much more easily maintained. Even more, it will be a great and fun activity for you and your family. Your children will enjoy playing with the dog - which might prove to be a good exercise for them too.
Dog balls will more than likely prove to be a great choice for you and your family: with prices ranging from $5 to $10, they are not a great expense and the fun and satisfaction they will bring you will probably make them among the best $5 you ever spent. It is best that you buy them at the same time as the dog - to get him used to the games and to a playful lifestyle in your household.
