my pitts agression toward me for only 5 minutes

Question
Im just asking for some advice on me and my pittbull. She is 1 yr and 3 months and the best thing to ever happen to me. I got her when she was 4 months and we have had the most amazing relationship. Well I had to move to my grandparents house for 1 month and i was forced to leave her with some people. They pampered and babied her the whole time with no type of rules. I went to pick her up after a month of leaving her there. She ran into the yard where i was standing, barked and growled at me but wagged her tail as if not sure about me. My first thought was she was mad at me and she was confused because she thought i had abandoned her. Understandable. well she finally came to me and greeted me but not like she used to. It was like she wasnt phased by me and when i took her in the car she was crying the whole 3 hour ride home. I tried to comfort her it didnt do anything she was too preoccupied by her surrounding and whatever she was crying for. Deep down i know it was them. They spoiled her rotten and i know i have noone else to blame but myself. My concern is she wont ever be the same with me. Do you think there is anything i can do and if so, what? Do you see something that I dont? have i really screwed her up? Its really breaking my heart. I love this dog more than any human ive come across.I was hoping you could give me some advice to mend my relationship with her or my broken heart. Thank you for your time. I hope you reply.

Some pitties are very vocal. I've got one in class right now who has a full vocabulary of growls, barks and grumbles - all of it just "talking". I can't say if your dog's reaction was aggressive without seeing it, but it sounds to me like it probably was not. Maybe a little conflicted. Changing situations can be hard on a dog - first going to live with strangers, then coming back to you. Difficult, but possibly unavoidable. When you had a problem with your living situation, you did make arrangements to keep your dog safe. Lots of people don't. So let go of your guilt. You did the best you could, and a young dog will get past it.
What you need to do now is work with her and train her.  Don't try to make up for what is past. Be a good leader now. Classes would be a good re-bonding experience. Give her kind, clear and consistent rules and routines. Most dogs are pretty resilient, though it may take a little time. Sandy Case BFA MEd CPDT www.positivelycanine.com
