Our sweet 7 month old wheaten BC has in the last 6-8 weeks developed an obsession for running around the backyard.
It started in late winter/early spring when the full moon was out and she was chasing shadows in the backyard. We did what we could to distract her. Then there was a birds nest of Miner Birds down the back and she would chase them - they would swoop at her and really annoy her. She has now created a dirt racetrack around our backyard as she constantly runs all day. We have a very big backyard (1352m), so doesn't lack space. She also runs the fenceline, particularly on the side where we have another border collie (male) - though she is desexed).
She is generally a very good girl. She was very placid and even shy when we first got her. She happily sits on her mat when she is inside. We have done puppy training and will continue to do the beginner training but to be fair, we have been very slack lately with school holidays, illness etc that have thrown things out. She has plenty of toys but these obviously don't provide her with much stimulation. We usually play soccer with her (she LOVES balls), take her for walks, go to the dog park etc. But (slap on the wrist) - it hasn't been consistent enough.
I know this is what Border Collies do - run.
Our major concern is that when we go outside, she won't come when she is called all the time - I am hoping this is the lack of regular training of late. Sometimes she'll be lying at the backdoor and when we go out to her, she jumps up and runs straight to her path on the grass out the back - it's like she is possibly trying to protect us from the birds????
My husband is really worried as he thinks she's gone a bit 'psycho' on us. We previously had two adult huskies who were generally very lazy and would just bake in the sun all day - so it's a big difference.
If anyone has any ideas, please, please help!
