AITAH for saying my bf is “not a good dog owner”

I 22f have been dating my boyfriend 26m for almost 9 months. He has this untrained 6y/o pug/boxer mix “Sizzy”, she basically does what she wants, no boundaries, no rules, he doesn’t walk her daily, only when he “remembers” (like twice a month) and she does her business wherever she wants INSIDE the house, never outside, and mostly at 2-3am when everyone is sleeping or right after being walked, stinking the whole place up. Jumps all over people and scratches your whole stomach the second you open the door, etc. She also wont eat unless there is someone in the house.

He is very defensive over her and will snap at anyone who talks bad about her, doesn’t correct her, he will literally make me scoot over if she wants to get in bed between us, or folds my legs at night to put her bedsheets under my legs (she sleeps on “my” side of the bed mostly) and although sometimes irritating, I guess some people are like that with their pets. But he always tells me “she is so well taken care of, right?”

He doesn’t cut her nails, so she has these long nails that bend sideways when she stands and already look round and long, I have trimmed her nails a few times out of pity, but he keeps saying he “prefers that a groomer does it” yet has never taken her from what I know the few years I have known him.

Well he was criticizing that at his job (furniture delivery) he sees a lot of people tie their dogs outside to open their gates, house smells of dog poop, etc. I was going to not say anything, but honestly it kills me every time I see her look so uncomfortable.

So I said “well you’re not exactly a good dog owner either” with a small chuckle, he asked me to explain myself so I said “look at her nails, that hurts-“ i grabbed her paws and showed him, one nail was already almost starting to dig at her paw “- she doesn’t know what pooping or peeing outside is unless I walk her with my dogs-“ he was already looking pissed “-and she is way too high energy to be stuck in a home all day, everyday without being walked, just because she lives indoors, you feed her and bathe her every few weeks doesn’t mean you’re in a place to judge others for how they have their dogs…”

Well he was pissed. He went on this rant about how he works five days a week and gets home too tired to walk her, that she is like his kid and that he’d do anything for her.

Now i know this is where I should’ve bit my tongue, but I couldn’t. So i said “if she really were a kid, I would’ve already called CPS on you”

He didn’t talk to me for two hours so I went home, now he doesn’t want to see me. He says we’re not broken up, but that I have “broken the trust he put on me, by letting me in his house”.

So AITA?
