YANBU @miseryguts1988 I used to LOVE dogs when I much younger. We always had a family dog when I was growing up, and one in particular I adored. (We had her from when I was 12 to 22.)
However, I would not have one if you paid me now. They are a tie, they're clingy, they're needy, they're whiny, they're noisy, they're smelly (yes they DO make your house stink!) and also, the vet bills are fearful. You have to have a LOT of surplus income to have a dog. (AND a lot of patience and time!)
Also, in my experience, some of the biggest areshats are dog owners these days. Some are OK, but I can think of more that are utter arsehats.
I have so many reasons for not being keen now.
- The neighbour next-door-but-two has her two big-ass dogs sitting on the front lawn some days, no tether or chain or gate, just free to run at anyone passing.
-
Every fucking day some arsehat walks past with their mutt and lets the mutt piss up my fence, or gatepost, or recycling box, or wheelie bin. (Or shits at the foot of my driveway.) Hilariously, they don't let the dog do it when I am watching. Funny that! 
-
Some owners just let their mutts bark bark bark and don't give a damn!
-
Some owners let their dogs shit anywhere.
-
I have lost count of the amount of times someone's mutt has run up to me and jumped up me, and sometimes barked growled and snarled, and pinned me against a hedge or fence.

On the beach a few summers ago, a loose dog bolted up to my backpack and dragged it across the sand. Everything fell out including my digital camera that got ruined because it got sand in the lens. The owner sheepishly ran off, leaving me with a ruined £300 camera.
Loads more reasons/negatives to dogs IMO. But yeah, SOME dog owners are right up there with MAMILS who ride their shitty bicycles, and men who like football, and who play golf. Selfish, and annoying. Shame really, coz it ain't the fault of the dogs, but I have very little tolerance for dogs now (and dog owners.)
