Found dog: Australian Cattle Dog (male, blue collar)

My husband found this very sweet dog on Galloway and 7th St NE near Fort Circle Park. He's wearing a blue collar (no tags) and, based on the amount of water he drank, seems to have been loose for some time. We took him to the vet, but there isn't a chip. Hoping to get him back to his family soon (or at least place him with a foster in the meantime)! (There's another recent post about a different Australian Cattle Dog -- it's not this one) UPDATE: Our sweet friend's owner has been found!! Thank you so much to everyone who chimed in with good vibes and offers to help -- this is a good corner of the internet :)
