Hello and welcome.
My husband wanted a Dogo Argentino too and although I have nothing against the breed I was already heart set on a Caucasian Ovcharka. It wasn't really a contest but we ended up with the CO. My hubby loves her more than life.
To lose a pet is one of the hardest things I have experienced and I know it must tear you apart as well. Sorry for your loss
