So I emailed the guy and asked why he annoys his dog so bad and if Niles is always aggressive like that, and this was his response.. To me he seems like a nice guy whos just trying to have fun, not trying to offend people..
"Hi and thanks for the email, and for the concerns! Always nice to hear that people are worried for Niles. Here is the deal with Nialator:
He is fine, it is not bad, and it is a game more than anything, both for Niles and for me. It started out when I was petting him and he sort of growled a bit and I stopped. He forced his head into my hand causing me to pet him more. I did and soon he growled again and I got scared and stopped, moved away and let him cool off. He came over to me and waited for more. I touched him ever so lightly, and went down his back very, very very slowly. When I get to the middle of the ribcage or so, he growls. I go hard and fast, maybe nothing, maybe he growls. I move to another part of the bed/couch/floor and he follows waiting for more. Now I can give him the eye and he will growl most of the time, and if I don't come to him fast enough he will come to me. I sometimes will say N I L E S very softly and every so slowly and he will growl. I am open to peoples medical or psychological/behavior opinions, but not to subjective views on this. I also Sing/Yell: W H OOOOOOOOOO (pause) W A AAAAAAAAAAANTS (pause) toGOOOOOOOOO FOOOOOOOR a WALK!!! and he sings/yodels as I get to waaaaants and g o o ooooo. Fun.
Not sure if this helps settle anything. Niles has always been vocal, it is not a demonstration of poor behavior at all. He also does not bite hard, it is all play, I just play it up for video and friends and show him off as ferocious. The only time he bites hard is if you run. He goes for the calf. Ouch."
