Malti~ I hope you didn't view my post as though I was pointing fingers at you saying you were wrong...DEFINITELY not! Just wanted to put that info. out there for the sake of information! Didn't mean to offend you if I did! I know what you mean!!! The very first time I heard it in one dog at the shelter, I literally flipped out, I had no clue what it was! Thankfully a vet thoroughly explained it to me, and now when I hear other dogs do it, I know what to do, and don't start panicking like I did the first time! :wink: Although, for anyone who has never heard it before, and doesn't know what it is, it is CERTAINLY one of the most frightening things to experience!!! :shock: Have a great evening!
