My daughter decided to buy a Kelpie (6 months) with her now ex-boyfriend and guess where her and the dog are now. She is 17 and working towards moving out around December. I am concerned about her dog as she is only here sporadically and although my partner takes Ruby to the park with our Cavalier (Scarlett, 1yr) she constantly tries to round them up even when Scarlett is disinterested and watching birds. We also take car occasionally of my mothers Cocker spaniel (Milady, 18 mths).
Ruby regularly knocks into people and has recently knocked over our nearly 3 year old son a couple of times. She bites the back of the necks of the 2 other dogs at the park and will round up anything smaller than her. She behaves better when other big dogs are around to play with but can easily wear them out.
Ruby has some training and can sit, lay down, beg etc. but we are concerned that her apparent under-stimulation (regularly rips things up in the yard) may lead to an incident with our 3 year old or even our 9 month old. She seems to walk well with the other dogs but will run away when we call her to put her on the lead and we have started to put her on a chain when our son is in the yard.
I really would appreciate advise and any examples that you may have.
