Birdwatcher, sorry to hear about the loss of your dog, blue heelers are the only dogs I’ve ever owned, so I know how it feels to lose one, once a heeler decides your it’s owner, there’s no dog more faithful, they happily accept and protect other family members but they always know who the real boss is, after my last one died I’ve not been able to bring myself to get another dog, I just realised that was almost 20 years ago when he died, he used to do this funny thing, where he would sort of listen to my girlfriend when I wasn’t around, but when I was there if she told him to do something, he’d look at me before he’d do it, then I’d nod or say go on, then he’d do whatever it was she’d asked of him, but not without my prior approval, but if I didn’t react he’d just go back to what he was doing, used to annoy the girlfriend no end.
