Dog missing in Angeles Forest near Mt. Disappointment

As seen with his hiking gear

Older photo of his face

Was out hiking with dog on Mt. Disappointment fire road when a deer ran in front of us. Dog broke his leash and chased after it. We were about one mile up from the trail head/gate. Dog is a male, brown/brindle boxer mix about 60 lbs wearing black and gold collar and an army green saddlebag/backpack. He answers to Tudou and is microchipped. Tudou is people shy but can be lured in with food. If anyone happens to be in that area this weekend and spots him, please message me.
