Welcome to the forums!

I'm not a roofer but I couldn't imagine laying shingles without felt underneath them.

I'm with marksr! If your roof never ever leaks, then no you don't need felt. But the purpose of felt is to protect your wood in the event of a leak. So it's like cheap insurance. I wouldn't install shingles on a doghouse without putting down felt first. AND metal edging.

sorry ,felt is used a a vapor barrier to protect the underside of the shingles from condensation,on an outdoor unheated shed ,it probably wouldn`t matter,it does make a better job though,once the water gets in ,it`s going to cause leaks where the nails are going through the wood,may offer minor protection ,but very little
