I know Crystalsmom posted it earlier - but there are really some great ideas in here! 
I see that it was freezing there overnight - in the 20s - and that it is suppose to be in the 40s but up to 25 mile winds today - which means the windchill will still like be below the freezing point. 

 I am so scared for Yoshi. I pray someone has gotten him somewhere warm. 
Was he wearing a sweater or a coat? did he have a harness on? Tags? I know the microchip helps - but so many people don't even think about that/or even know about it. I know some vets don't even check for them when someone new comes in with a dog. 
Do you have people to help you look for him??? You need an army with these little ones 
Praying that where ever he is he comes back safe & sound very soon,
