This is not what I need this week. I just put down my 12 year old Golden retriever on Monday. 
Quick backstory: We have a fenced yard. The side that divides my house from my neighbors is lower and you can see through it. My neighbor (Bob) is always teasing my dog. Walter (dog) always growls and barks but can't get to Bob b/c of the fence. The type of teasing on Bob's part scares Walter. He'll pretend to lurch forward and Walter runs away.
Today I took Walter for a walk. Bob was also out walking and started to approach me. As he got closer Walter growled. Bob still continued walking forward and walter jumped up and bit his arm. Hard enough to break skin.
Walter has never bit anyone before. I'm so shocked. He's been in lots of situations where he's been startled by the kids (like them jumping on his back) and he's never done anything.
I just can't believe this happened. My neighbor isn't mad, thank God but I just feel awful. Add that to the crappy feeling I already had this week b/c I put my other dog down.
Any advice has to how to handle this?? Should I be worried I have an aggressive dog?? FTR he's a golden doodle.
I have a call into my vet and I'm waiting to hear back.
