Hi all, I've randomly posted here and there but never introduced myself.....I'm newly married ( tied the knot in April) and work in higher Ed. My husband and I just brought home a rescue on Thursday. She's approximately 11 months old, American Bulldog mix, big, strong girl about 60 lbs or so. This is my fist dog and I've never grown up with dogs so she does things that scare me bc I'm not sure if its aggression or play. She's hard to walk, a huge puller- my shoulders and elbows hurt from tying to hold her. Today we tired her out with a looking walk and she was very mouthy when we got home, no growling, just opening her mouth and trying to bite out hand/ arm but tail was wagging. We say " no!" And out an appropriate toy in her mouth. We are tAking her to obedience class on Tuesday. Her early life is unknown but the woman who fostered her swore on her life she has zero aggression and has so much potential. I hate being nervous. She does well for my husband but not me so much. Any thoughts or suggestions? Is she still a puppy? Is she maybe still adjusting to our home? I want to be a responsible owner and help her be the best dog she can. We wanted to rescue bc we thought it was a good thing to do.
