Well the Argentino in the name just screams to be named after someone from the Argentinian(?) Men's Basketball team. I would go with Andres. But something like Manu or Carlos would be cool. That's just my opinion. Or maybe after something that you think is cool or means something to you.
I named my Bloodhound, Lynyrd. Because I love Lynyrd Skynyrd and when I think of dogs from the south I think of bloodhounds. I sure do miss that guy.
My dachshund is named Duncan. Idk why I just liked that name and it's not very common. After I looked it up in an encyclopedia I guess the name means, "brown warrior" which made me lol. When I get a long hair dachshund later on I intend to name it Rommel. Since Erwin Rommel was a lover of dachshunds.
**My personal favorite and go to for big badass dogs is Bruce. A friend of mine has a Ridgeback named Kratos, but I still call it Bruce. Good luck with your new dog.
