Has anyone experienced something similar? What did you do?
Well, not the disagreement with the SO. But I have a vaguely similar pair of dogs right now, and a two dog limit (unless I get wealthy suddenly and can afford to buy my own place). And...I make it work.
Meg's mostly retired at 10; she doesn't like to train anymore, so we don't. She'll run a class a day or maybe two if I'm going to a trial.
Gusto was supposed to be my Next Big Thing for agility, and as things like that tend to, it didn't really work out right. He's had some physical issues, although we seem to have a handle on it now, but more than that, his stress issues have been a big hurdle. Probably a combination of his temperament, my mistakes, and some less than ideal training advice. In a perfect world, I'd probably keep him as my fun tricks/hiking dog, and I'd have a puppy already with whom I'd be working for agility.
But it isn't an option, so I keep working with Gusto. I travel 3 hours each way to a trainer who is helping us with the stress issues and agility in general. I've spent the last year going back and trying to fix the mess I made the first time around. I'm trying to teach him to love agility and not let it be a stressor.
And in a way, it's all good. The skills I'm learning with him are going to be a HUGE benefit for any dog I get in the future. I'm getting to be a better trainer, he's getting a ton of work that he's enjoying, and we are moving forward - albeit more slowly than I might have hoped. I understand him and his needs more than I ever have before, and I think we are both a little more in love with each other than we were even six months ago.
If another dog is a couple years off regardless of your SOs feelings, I'd be working with Chloe. It is only going to help you when you get The Next Dog. She may be worried about working in front of other people or not driving to obstacles right now - but learn how to make those rewarding for her. In general, I'm not a big fan of sitting around waiting for The Next Dog. Because that one is going to present you with obstacles as well, no matter how carefully you select it. And then it will be all about waiting for The Next Dog 2.0. Barring serious physical reasons - I'd train the dog I have, and see where things go.
That is probably not at all what you were asking about - but that's what happens when you spend 3 hours in the car by yourself driving home from an agility lesson! Way too much ruminating about life and dogs and such.
