Being classified as medium to large sized dogs, the Afghan Hound and Collie each require about an hour each day of actual activity. Therefore any dog that is a mix of the two will have the same activity level and exercise needs. Playing ball in the back yard, provided your yard is large enough, is an excellent way to keep him moving. However, the Collie is a very social dog and will need to have social interactions with other people and dogs to keep him happy. The same may be true for a dog that is part Collie. Dog sports are an excellent to keep your dog in shape, create a strong bond and give them the socialization they need and crave.
