Thanks all for your advices and welcome!, we've been thinking about getting another lab, maybe a black one (chocolates are very had to find here), that keeps up with Cousteau. Thanks Rachel for bringing up the fact that "2 dogs=3 dogs", we never considered it that way! : )
As for shelters, i'm sorry to tell you that here in Venezuela they aren't as widespread as they are in the US, in fact there aren't any in the city we live in (i know, is such a shame). So the dog lovers (as us) take the time o feed some of the stray dogs and give them some love...i can tell about that later.
Anyway, thanks a lot, i'm considering all your advices!!.
