Well, I've been away from my dogs for 10 days so everything about them seems perfect right now haha.
Aussies are my breed of choice now, and I can't really think of anything major that I'd change. I hope I never end up with a supremely hairy one and I wish they played a tad less physically. Journey LOVES to body slam everything and I worry about her safety and also feel bad for other dogs when she does it to them, and I don't really appreciate the random bursts she inflicts on me either haha. Also, Journey is not a barky dog except in certain situations, but it would be nice if the breed as a whole wasn't barky. But yeah, all in all, I love them just the way they are and there is nothing about them that is a deal breaker. And physically, I don't like extremes at all (too heavy boned, too much coat, too big or alternatively some of the super slight, naked or curly coated, teeny tiny dogs barely recognizable as Aussies). I like a dog somewhere between extreme show and extreme working. I love Journey's build right now and hope she maintains her athleticism and leggy-ness as she matures. I'd be super happy just to have all the rest of my Aussies from here on out to be a lot like Journey. She's about as ideal as it gets for me in a dog.
And I kind of hope my next one has a tail. I love the look of no tail, but for the activities I like to do with my dogs, I'd feel more comfortable with a tailed dog. It's not a deal breaker for me, but when comparing Journ and other Aussies to the tailed Aussie I know, I sometimes really wish Journ had one too.
Other breeds...
I really love Koolies still too and want one for sure. The only thing I'd change is the barking. I feel like they bark a lot more than I am used to, but oh well. Barking is manageable.
And I still love Tollers, but I wish it weren't so hard to find a stable, solid nerved dog. I don't think I'll even have another at this point simply because of that. I've just been around way more spooky weird Tollers than nice ones unfortunately.
