AITA for wishing my "sister" had stayed a runt instead of turning into a linebacker?

Am I the asshole for wishing my "sister" had stayed a runt instead of turning into a linebacker? Good morning to everyone except people who leave one second on the microwave without clearing it. You are a chaotic monster. Dexter here. God's own prototype. Christie finally finished her latest exercise in futility. Dropping 200 bucks on a doggy DNA test. When she got the results, she stared at the screen, wide-eyed and breathless. Turns out, I'm 100% husky. Did she really need a laboratory and a spit swab to figure that out? Was the glass shattering screaming at 3 AM not a sufficient clue? Christie cued at me. Oh, Dexter, you're purebred. No, bitch. Being 100% husky doesn't make me special. It makes me a high-octane weapon grade manipulator who thinks his primary purpose in life is to destroy linoleum. Then she checked Darcy's results. 81.1% Siberian Husky, 18.9% Alaskan Malamute. Well, that's fucking wonderful. I've been watching that seven-month-old parasite for a while now, and it's honestly insulting. She's all stem, no lobe. She's already as tall as me, but she's got these long lanky legs that make her look like a fucking giraffeoid nightmare. When she looks up, I imagine her eating foliage off the top of a tree. She is built exactly like a phospholipid. Every morning she wakes up, looks in the mirror, and decides she's going to grow another inch just to trigger my deep-seated insecurities. She's size-maxing herself into a draft horse. The humans are ignorant to the fact that Alaskan Malamute is actually the scientific classification for a chupacabra. Darcy's just waiting for a full moon to stop pretending to be a dog and start singing the neighbors' goats. When Christie announced her results, she didn't even care. She looked at Christie with the same blank stare the cat gives me when I try to ask it questions. She just let out that high-pitched, manic yodel she does. It's bad enough that the markings on her face look like an elder scrolls map designed by a lobotomy patient. Frustrated, I did any deeply petty, spitefully husky would do. I pissed directly on the bed. Christie shrieked and called me an asshole. Oh, sure, Christie, blame the guy who's holding the compass. So TikTok, am I the asshole? Dexter out.
