lost dog (Billings (lockwood) Mt)

Still looking for our rescue dog that got out of our yard.
He is a 10 to 12 year old Chihuaha.
He is Brown/Tan with grey face.
He is very friendly.
He is a teacup so very small in statue.
He has no collar as he got a chip that day from Lockwood vet.
So his neck was too sore for collar.
Since we had only had him a couple days and rescued off the streets out in Lockwood We didnt know his name .
He can be on Canary.
Bluebird or off dickie rd.
If you have seen him or know where he is please call show contact info or show contact info .
Thank you
