We think she's about a year or so. The people we got her from had her for a few months (living in a condo, so no yard, and a newborn), and they got her from someone else who wasn't really taking care of her. There was also exactly zero medical records, so other than the fact that she's menstruated and therefore not spayed, we knew nothing about her.
Fortunately she's a happy, healthy dog--she just doesn't know how to dog at all, other than being mostly crate trained. There's been some accidents, she chews on just about anything she can get her teeth on, barks at everyone who walks by (we live next to a school and a park, so it's a lot), and pulls so hard on the leash the kids can barely hold on. To be honest, I was perfectly fine not having a dog and would've been fine never having one. I'm a cat person. I'm fine with having one of course, especially since Katie and the kids really wanted one. I wanted one pre-trained, because I want to do as little work as possible with the dog, which clearly isn't gonna happen. That's the trade off, though--get a dog for free instead of paying exorbitant adoption fees from a shelter, then deal with all the untrained shit.
We all had a hard weekend for a variety of reasons, and honestly a lot of our shit probably rubbed off onto the dog and that caused her to go ape shit too. Today was much better and I'm 95% sure we're keeping her. I'm still dealing with... I don't wanna call it PTSD because that's dramatic as hell and insulting to people who actually have it, but I'm dealing with SOMETHING as a result of all the change that's happened this year. It's not as bad as it was during the summer, but it's still there. Adding an untrained dog to it probably wasn't the smartest idea, but it's what happened.
