If your talking about bush growing which i think you are, not backyard then forget about dogs, you want to be as quiet as possible in there and who is going to feed and give the dog water?. Guns are no good as you wont be there when it happens. Heads on sticks wont stop a ripoff ,they found the patch and nothings going to stop them.
1-the main thing in not being ripped is to only working in early morning, do not visit in pm hours ( trail bike riders ,kids out of school etc), also hide the car. The car is the give away.
2- do not grow with a partner
3- dont show anyone
These are the reasons people get ripped off. Since i made these changes a few years back i have not lost a leaf. Prior to that i lost dope every year.
