is it allow puppy to play FIRSBEE? or it is better when the puppy 's bone and joint totally mature? my friend has a border colli puppy, when it is the best time to begin such a high jump sport? thanks a lot  、

please wait until the puppy is totally mature if you wanted to play with a frissbee i personaly wouldnt at all because one injury from jumping for it can be a life time complication for the dog especially back injuries

Ditto we let our collie play with a frisbee and a ball chucker result OCD in his shoulder joint £3000 op and on tablets for life before he was 5 months old.

He's active but his bones are too immature for the constant jump and jolt action. We found out the hard way.

ok  I know now, thanks a lot for advise .
