You perverts, you thought i meant the sacks under his rear -.-!!
Well your wrong, I am talking about Tennis balls and meh question is, how long can your dog play fetch? Any other game you play with tennis balls besides fetch?

HA Ha ha, You made me look ... but only to be sure the post was "on the up and up" and not b/c Im a perv!!!

Neka will fetch a few times before she gives up ... Patchs on the other hand, will fetch until she drops or gets board.

I admit this made me laugh! My dog will chew on the balls but he won't chase after them. He is extremely to lazy to keep running back and forth for it!! I love to play tennis in the summer and every year I buy new set of balls and I give my used ones to my dog. I think once I bought a set of balls for my dog from the Dollar Tree, they were flavored balls like roast beef or hamburger or something like that.

You can actually play for as long as your dog wants, usually the more the merrier because "a tired dog is a good dog".

As for more games? There are a few, here's a list of 22 games you can play with your dog, some don't necesarily say to use a ball but you can most definitely incorporate it in the game http://k9domain.org/games.aspx
