Lost Shihpoo Goliath on Croft St, Tacoma!

He is a shihpoo mix. 8 yrs old, Name is Goliath. has shorter hair than in the pic from being shaved a few weeks ago. Face hair is still like in the pic. I had him out to go to the bathroom and Door open but didn't notice him running after a neighbor driving out as I closed the back yard gate. Thought he went back inside and went to bed with the wife. Went looking all day 40 mins after we were aware he had gone chasing the neighbors car down Croft per the neighbors security cams.
