Blanket odor - help

I have 2 large dogs and bathe them regularly. I also deep cleaning my washer often and have tried soaking blankets to remove pet odors however all of my blankets still reek!

The blankets will come out of the wash smelling fine but after sitting out for a little bit will smell so bad especially if any windows are open! I live in a humid environment so maybe thats a factor??

I’m at a loss of what to do. Looking for all tips and tricks please!
