Hi Mary nice to meet you then!
Sure that I know Chile and I cannot speaks spanish too.

You know, I have read something about it too, but do you know what I think of it? Picture that I am in the streets and he start to bite something, will I get the squirt and squirts on the dog in the middle of the street with people looking at it? This is bizarre!!

I think I WILL have to show him whos the daddy here! hehehe
With some power NO's and sometimes grap the scruff of his neck saying NO.
I am doing it yet and sometimes giving him some timeout's.
And I think soon or later he will associate the No with something bad. (GOD HELP ME)

Any other advice?
