OP, keep in mind that just because something is in your parameters online, that it doesn't mean it's likely to get it. I'd look at things like how many people have contacted the realtor via the posting or if it's an "open house" (when like 30+ people might as well get a raffle ticket). Sorting by new helps you be first in line on the ideal apartments. It's very similar to how seeing a house listing and having an offer accepted on a house are very different parts of a home buying process. And yes, this is true even if income and credit ratios are good because the application just isn't going anywhere if several good candidates are ahead of you.

Dog friendly skews heavily on the side if new builds, though some house rentals are more friendly. I don't see a ton of dog friendly multifamilies, but that's just my experience over moving several times. My friend is moving into a dog friendly, in unit w/d new build and the going rate is 2k/studio. I've shared basement laundry with buildings of 5-10 people and it's hardly an inconvenience.

Having a dog here is unfortunately hard mode in an already extremely hard process. Good luck.
