Growl: Play vs. Aggressive

Question
QUESTION: Hello,
This is in ref to my earlier question on the same topic.

1) Is the growl at 2:11 of this video ( http://www.youtube.com/watch?v=qwArZKX6l... ) playful or aggressive?

2) What are the signs you are looking for to determine if its playful or aggressive growl?

Thanks,

Jatinder Kalsi

Answer
Hi, Jatinder,

It's hard to tell from the video because the barking/growling isn't being done in a play context. I can sort of hear what you're worried about in the low tones of Bella's voice. To me she sounds more frustrated than actually aggressive though.

I hope this helps,
LCK

(By the way, I also taught my dog to bark/count to five; it's really cool...)
