Hello, my name is Easton. I’m new here. I have a year and a half old female boxer named Harley. She is the sweetest puppy. Super loving and affectionate. She’s a boxer through and through. I’ve grown up with boxers so I’m not new to the hyperness or the attitude, however the random spots of aggression towards my parents new rescue pitty ( his name is Fin) is not something I’m sure I know how to address. She’s always been rather nervous, but now she almost has too much confidence. Anytime me or my husband try to play with Fin, Harley is right there with us. Sometimes she’s fine but randomly she just nips at him, or if he comes up and sniffs at us and she happens to be close she nips at him, snarl and all. She and my parents former boxer (he passed in November) did not get along and because of that we had to keep them separate. She’s great with my other dog, (pointer mix named Rigby). My parents pup is the sweetest and has stolen all of our hearts. I would love to not have to leave Harley at home everytime we go over to their house. Any sort of help would be wonderful.
