Well... it was a one time thing... but she killed my bird. That was annoying.
Otherwise... her barking. For some reason barking just turns a switch in my head and I just want to start screaming and beating things. I have no idea why. I don't mind whining, she'll talk to me and I love her to do so... but start barking, and it's like my eyes roll back and I see red. I obviously don't start screaming and beating things... but... I can't stand it. And of course... for her... every single bird is something that needs to be yelled at.
As for the new pup (who is the GSD, albeit a mix, in my life), her most annoying thing is that she's a puppy. I like adults. I love her... but I'm so ready for her to grow up.
