[name_m]Just[/name_m] wanna see what names you would name a pitbull.
My Top ones are:
Tank (M) [name_f]Dixie/name_f
[name_m]Chevy/name_m [name_f]Cleo/name_f
[name_m]Zeus/name_m [name_f]Luna/name_f
Bullet(M) [name_u]Aspen/name_u
[name_u]Dakota/name_u [name_f]Daisy/name_f
No such thing as a pit bull. sorry. its a personal pet peeve. there is no recognised breed called a pit bull. for arguments sake i think most people assume it to be an american stafford shire terrier but ive seen people call all sorts of dogs pitbulls and they are all wrong. that being said i like
Smiley and Cheese that could go for either gender
[name_u]Beau[/name_u] for a boy and [name_f]Poppy[/name_f] for a girl.
Boys:
I like [name_m]Zeus[/name_m] a lot too! I also like other mythology names like [name_m]Hercules[/name_m], [name_m]Thor[/name_m], [name_u]Mars[/name_u], [name_u]Neptune[/name_u], and [name_m]Pluto[/name_m]. Others include [name_u]Harley[/name_u], [name_m]Bucky[/name_m], [name_f]Marvel[/name_f], [name_f]Copper[/name_f], [name_m]Cooper[/name_m], [name_m]Ajax[/name_m], [name_m]Nero[/name_m], and [name_u]Blue[/name_u]. Also I love [name_m]Argo[/name_m] 
Girls:
More mythology names… [name_f]Juno[/name_f] and [name_u]Nike[/name_u], and also… [name_u]Blue[/name_u], [name_f]Shasta[/name_f], [name_f]Luna[/name_f], Eclipse, and [name_m]Zel[/name_m].
Also, the American Pit Bull Terrier is a registered breed with the AKC, so it is “a thing”.
I like [name_u]Aspen[/name_u] and [name_f]Daisy[/name_f]. I’m not huge on any of the male names you thought of. I tend toward more “human” names like [name_m]Howie[/name_m]
[name_m]Zane[/name_m]
[name_m]Rupert[/name_m]
[name_m]Seamus[/name_m]
[name_m]Norm[/name_m]
There is something I find relatable about a dog with a “human” name. (that list was a group of random thoughts)
I would use names of Myth like Hades, [name_m]Apollo[/name_m], [name_m]Zeus[/name_m], [name_f]Nyx[/name_f] etc and names like [name_u]Zen[/name_u], [name_u]Ren[/name_u], [name_m]Kylo[/name_m], [name_m]Saber[/name_m], Brax, [name_f]Niva[/name_f], Sabby, [name_f]Nahla[/name_f], [name_f]Aura[/name_f], [name_f]Cae[/name_f].
Some people are very nervous of Pitbulls and so I’d tend to totally avoid names that sound in any way fierce. I think I might go the slightly silly route:
The boys:
Fido (maybe spelled Phideaux to give the vet a laugh)
Bonzo
Spot (preferably if he has none at all)
[name_u]Bert[/name_u]
[name_m]Ernie[/name_m]
The girls:
Birdy (well, [name_u]Bert[/name_u] and [name_m]Ernie[/name_m] made me think of Big [name_u]Bird[/name_u])
Doughnut
[name_f]Bunny[/name_f]
Twinks
[name_f]Kitty[/name_f]
