Erratic behavioral problems w/ 6 month old female - Page 1

I posted a few photos of a female working line GSD in a couple other threads. Tonight I am looking for any suggestions and insight into some strange behavior from her.

Molly is and always has been a dominate and at times aggressive pup. When I picked her up at 7wks old she snarled at my 4 month old male GSD when he sniffed at her. I did not worry much since she did very well on Leerburgs puppy test and showed no aggression or fear towards my husband or I just curiosity.

I have read that it is seldom that a pup younger than 8 months has a defense drive so I thought her breeder was FOS when he told me that she barked at visitors at less than 7 weeks. I was shocked to see her attack a wet vac at 9wks, throw herself into a car window after teenagers at 3 months. Then distressed when she snarled & snapped at me when she decided she didn't want to be brushed anymore. At five months she bit my hand when I reached for her collar , and she has snapped at me mutiple times when I gave her corrections with the prong collar. She will bark at every visitor to my home and living creature that passes my house. However, she will crawl into the lap of and give kisses to anyone who I have welcomed into the house without any aggression at all...  


 As far as her obedience,  when very young  she would ignore my husband who rarely had time to work with her but, would listen to the basic commands I gave her with  bouts of disobedience (she would refuse to lay down and TRY to stare me down during corrections) She would do this once or twice a week and then be perfect in between after she realized that I would make her do it and she was not intimidating me. Then after a while the corrections with her normal collar didn't phase her. She would just stare at me while I gave her correction after correction. The prong collar kept her under control for the most part but, when she knew it was not on she would occasionally disregard me. So, a few  weeks ago I bought a training collar and she became the perfect dog....for a week. She went from having multiple daily incontinent episodes in the crate each day to totally house broken IN ONE DAY! She performed commands at the drop of a hat, showed no aggression and was just perfect. She even seemed to act more goofy and happy than I had ever seen her act before. I was thrilled to see that she could received just one appropriate correction and then move on.


That was until Sat when she snarled at me and bit my arm when I pet her while she was chewing a bone.  I was sitting next to her in a chair and began to pet her while she ate. She was friendly, wagging her tail and calm at first. Once I was satisfied that food aggression wasn't a problem I turned around to read and began to pet her without looking at her. When I heard her snarl I looked at her in time to see he lunge for my arm. I gave her a correction via training collar and then flipped her on her back and stared her down. The next morning she voided in her crate and again began to ignore commands in spite of corrections and tried again  to stare me down...



When she showed the first signs of aggression I read a few Leerburg articles on dominate dogs and dealing w/ aggression.  I made several adjustments to her training such as allowing her nothing for free: food, toys and time out of the crate are earned with obedience. Aggressive behavior results in corrections via training collar then isolation. I have made a point to work with her while eating her entire life. I would play with her kibble, raw food and toys looking for any guarding or aggression and until this week saw none.

The confusing part of her behavior is she is not a nasty dog if that makes sense...  She loves to crawl into laps
