Hi all im looking for some advice for a 1.5 years old border collie. On several occasions this has happened: she runs out of the field and goes back home but not before jumping out infront of cars and nearly getting run over. The problem is that she doesn't listen outside, if she sees a person riding on their bike she will chase them and bite even while im calling her back - when she gets something in her mind she blocks everything else out. She doesn't want to come back so i can put her lead on to go home, she will come close and then run away as if she is teasing me. If she sees a shifty guy walking past she may growl and bark at him. sure it makes me proud that she is trying to protect me but it isn't not fair on that guy. in the house she is good as gold, puts her ears down, sits and shakes my hand but outside she is a master in her own world it seems and no one can stop her cuz she is super fast! so as u can see we got problems with our border collie. we got her a face leash thing and have been using that in hope that she will stop pulling but i think it is just because she is excited to get to the park. we take her for a walk every single day but still she has not gotten out of this habbit. we thought that she was growing up and getting over her problems but it she ran out of the park again today and nearly got run over twice! it seems that she will have to stay on the leash until she is about 3 years old, but really must it be like this? i feel sorry for her sometimes because she wants to play. We are looking to mate her this year and we hope that she will become more responsible and act sensible when we take her for walks in the future. do u think this will work? After this incident today i signed up to this forum and im looking for advice. Thank you! Sadie when she was a puppy. Has one blue eye and one brown eye. Sadie grown 1.5 years old.
