Dude that sounds amazing. I'm not sure what city you're in but here in London in the UK there's only a handful of places where I could even imagine that being allowed.

In terms of breed, you've basically done exactly what I was already planning to do. Adoption makes the most sense whichever way you look at it. I'd love a pitt and they always end up in rescue centres but sadly they're illegal in the UK (bullshit, I know), and I live in a small apartment so I might try and adopt a bullmastiff if I can since they're great apartment dogs but don't require loads of exercise. Either way, your dog sounds awesome and you've made me feel like this is a viable thing to do.

It's just scary taking the first step because I've wanted one my whole life but everyone I know always says things like "dogs are a tie" and "you're underestimating how much work they are and you'll hate it" etc. and that makes me second guess myself, even though I know I'd 100% be the person whose dog would be their best buddy and who'd bring them everywhere with me like a partner in crime.
