So I am kind of reaching my wits end with this girl-I actually found myself browsing at shock collars and doggie boot camps online today. We had an in home trainer and did everything she said, but she is still not behaving (our trainer and our breeder used the term "very independent for a berner"). Heidi is 9 months old, about 90 lbs, strong as an ox, and thinks she's the alpha no matter what I do. She pulls so hard on her leash during walks that she pulled me down once (and I certainly can't ask anyone else to walk her when we go away in January). She doesn't come when called and counter surfs. When she wants attention (doesn't need to go out or need food or water) she will come over to us while we are sitting and insist on trying to climb into our lap and smacking us with her giant paws OR she will chew or "bug-check" (tiny little surface bites that really pinch) our feet, legs, shoes, hands, clothing, or whatever she can reach. When we tell her off, leave it, or no, she growls and barks at us and then goes right back to doing it. Or she will just stand there and bark and bark and bark until we yell at her and put her outside. She has also started annoying night time behavior : we can't let her sleep upstairs with us because she always poops on our bedroom carpet even though she never goes anywhere else in the house. When she's not tired, she will cry and eventually bark at the bottom of the stairs. I have checked to make sure she doesn't need to go out or need water. She only wants to play, but it's at around midnight!! She is not an aggressive dog (she doesn't try to hurt us) but she is definitely trying to challenge me as to who is boss and it seems she sometimes thinks I'm her chew toy. And let me add that this attention seeking behavior is CONSTANT Except when she is sleeping. I really don't know what to do.
