Is this normal dog behavior?

Trust me, if you had a relationship with your dog beforehand, she wont forget you. I go to school every day and play with her in the afternoon and then i went away for 7 weeks to europe. She was so pleased to see me. I rexommend that tou spoil your dog alot and show her just how much you love her. This is going to aound weird, but it sounds like your dog is holding a grudge on you because you left her! It will probably wear off when she realises you're here to stay!
