Thanks all.
I did hear that about the walking. And TBH she probably isn't walked as much as she should be. Well, I don't walk her in town at all. Every week or fortnight we go out to my parents block & she, along with our bigger mastiff & mum & dad's jack russell get all their exercise. There's 7 acres out there & they spend the whole time running & exploring it all, playing together. We walk them around the 3 dams, probably 3 times a day.
Its not possible for me to walk her here often enough. Someone said if thats the case I shouldn't have a dog, but I have her for my kids & safety. I'm home alone most nights & feel 100% safe knowing she'd bark if there was something worth barking at. I think she gets what she needs. But I feel different to most as I was raised with chain mad dogs...
