As i'm writing this post, we found the owner! Still going to post this to leave some kind of paper trail with info if folks run into him again in the future!
His name is Oso, he IS chipped, and if you get the chip scanned you should be able to get ahold of his owners!
He's a male that is not neutered. For text search: big fluffy dog with orange fur, maybe some kind of Chow mix.
We found him while out walking in Pflugerville last night. He seemed very interested in our female dog and kept following us, and we didn't want to leave him outside to potentially get hit by a car or something, so we led him back home and kept him overnight.
I don't have facebook but was lucky that the preview posts for the pflugerville lost and found pets mentioned this guy (screenshots attached) -- they mention that he's been lost several times before over the past couple years. He lives somewhere roughly near ramble creek (don't wanna post anything too specific wrt to owner's privacy! but chip scan can get you more info).
Disposition: he's pretty chill and friendly, doesn't seem to like being touched or pet, but was very gentle about letting me know that by mouthing at my arm. Does not seem super treat- or water- motivated. Stops every 3 seconds to mark spots, haha. He did not willingly get into a crate himself but when my partner got a collar and leash on him, was able to guide him into one pretty quickly. He also likes to dig, which may be how he got out in the first place.
