Lost Bulldog-Beagle Mix in Phoenix Area

75% English bulldog 25% beagle Male Brown back/body, white belly/chest, black on face around eyes I was working in the back yard with the gate locked and the only possibly way my baby boy could have gotten out is the homeowners Neice at the house I’m staying at had to have left the door open at some point. He got out Sunday October 13th, around 7:00pm. I doubt he was on the street long and I believe someone in the neighborhood or nearby had picked him up. I’ve posted him everywhere every day and no information or direction
