Frisbee
This is a wonderful, democratic sport for dogs, when they must catch plastic discs. It does not require a special place or investments, but brings a lot of fun to four-legged athletes and their owners. Frisbee gives dogs the opportunity to play and maintain a good physical shape.
The best breeds for playing Frisbee are Border Collies, Australian Shepherds and Fox terriers, as they are active and usually very jumpy. For obese dogs it will be difficult to play Frisbee.
