They told me that border collies, do that with sheep, all the time, they nibble in the behind legs, to make them run faster, or go hurry up. Frey does this with my front tyre. When I was running him with my bicycle, a long time ago, he ruined two of my front tyres.
. It is hard wired in his system so it will take a while to make him stop doing this.
But now, no longer able to ride a normal bike, we do it with the sinclair. He cannot get there (at the front tyre) anymore.
. It will take a little while for him to see the pointlessness of his attempts.
And Alex, i dont understand, "poor Frank".
First my dog's name is Frey, and second, this was not a long run at all to him. Poor Frey, course he is not aloud to bite my C5 sheep in the legs, I would understand that. If I take my C5 out of the shed Frey starts getting very, very, excited and brings me his leash. sorry for him that is not the only reason I have my C5. Than he is really disappointed.
Its the same with frisbee's I can throw them for hours but it is never enough for Frey.
He is almost as fanatic with these things as I am with my C5.
