This dog was found wandering around Loma Alta Park today: Bonnie gives us the details:
Red Siberian Husky - blue eyes. Young unaltered male. No tag, flea collar and harness. Was found wandering below gym next to Loma Alta Park. He was then tied up next to the office (with water) to keep him from wandering. Someone called Humane Society who said they would be picking him up today. I was notified of it by a resident who sent an email/photo of the dog to our neighborhood mailing list.
Since the Pasadena Humane Society doesn't cover Altadena, you may want to check the Baldwin Park animal shelter as well. Hope he gets home.
UPDATE: Puppy's home now.
