I have a three yr old and a 51/2 month old.  The problem i'm having is that the three yr old has run beside a bike and pulled the scooter for a little while  and now she does not seem to enjoy the scooter, she will stand and look at me as if to say get that away from me so i thought by trying the pup with a mini scooter and my son to see if he enjoys the idea.  I have no problem with him he get very excited as i get the scooter out the garage. I would like them to run together but at present i dont see this happening.  Any ideas on what to do i would be very gratful.  also does the confidence come with time as i will admit these are my first sibes but i am a grate beleiver in having a dog that you can work to the job it is suppose to do.  Ok my B.C. does only do obedience and i have no sheep otherwise he would be doing his job, but with sibes i couldnt have any sheep so i will carry on as i am but hopefully with a little help on the pulling matter i could live a happy life with my dogs doing the job that they were bred for.
