This is the guy I posted on July 20th, as a beagle mix. Turns out I had already posted some other pictures of him on July 5th. Grr. My bookkeeping isn’t perfect, but it’s not usually that bad.
I think I was wrong on breed ID though. The more I look at him, the more I think he’s an Australian cattle dog.
Oh well. I still have a couple I didn’t post, so here they are.

Another reason to think he's an ACD mix: he sure seems pretty ball-obsessed. He stood there like this watching the ball for minutes at a time.
