Hi, I have an 11-month-old female border collie called Meg and she is quite the handful. She is constantly jumping up on the table with food, is very skittish around other people but loves other dogs, is not at all good on the lead out on walks and she just freaks out, she is always chasing our cat because she has so much energy and is always annoying our 7-year-old small dog because of her energy we are starting to consider whether get another Border Collie would be a good idea to help control her energy and make her feel less insecure when out and about or with strangers. Would it work if the other border collie was younger but a lot bolder and much more friendly?? Or could this just be double trouble?? Please give some advice.
