I have a puppy that I'm sure is part Border Collie about 6 months old. She likes the frisbee alot. She chases it and sometimes catches it..then she will lose interest sometimes, not completely just not very focused... I throw lots of rollers and try to keep her interested... I think she is tired...

So my Border collie benji is a fetch addict at 6.5 months of age. Returns the frisbee every time and is getting better at catching it out of the air. The only problem is that he doesnt chase after it while its in my hand. He wont circle around me to get a running start. He just stares at me...
