Hi Carol ~ I'm 43 & live with my 2 children on 100acres in the Australian bush. I look after animals, orchard & gardens. It's not easy, especially tasks where my strength is frustrating, but then I swallow my pride & ask a neighbour for support. I have the big dog, she's fantastic! What to do if she is barking? Yes, you get to know the bark....& I know my property like the back of my hand. (I would NEVER get out my gun, it would take far too long....!), but it is helpful to know karate! (also helps with confidence) They wouldn't know what hit them!! Goodluck, it's worth every moment.
