My dog sugar a golden labrador behaves very strangley after I take her for a walk. Right after I take her for some reason she feels the need to go somewhere to be alone, almost as if she's hiding from something. A couple of days ago I found her under our deck burying herself a little hole. This Behavior did not start until recently. Here's a little background info about here that might help with this problem. We have had the dog for 4 years now she's in great shape. We picked her out from a shelter were they took her from a abandoned animal hospital, she was basically left to die. Around her family she is incredibly affectionate and a lovable animal she's cuddling up by my feet as I write this

. Around other people she doesnt know she completly avoids, them she can now be within a foots proximity of a stranger. But should they try to pet her, she runs to the other room.
