Ah, that’s unfortunate. If you say you’re happy in your SUV then showing you places to live that aren’t your SUV isn’t very helpful. Having a discussion about whether you’re aware of and prepared for any risks associated with living in an SUV could be productive - either you’d learn something from social worker’s knowledge of many people living in vehicles or the social worker could be reassured that you’re not in a terrible situation.
Do be careful out there! I hope you’ve got enough cash in the bank or enough credit to recover if someone messes with your SUV.
All of the above plus: allergy covers for pillows and mattress, nasal irrigation with a neti pot or squeeze bottle (they sell the nasal rinse bottles and saline mix near the allergy medicine at the pharmacy), bathing your dog frequently . An allergist will have a really specific list of recommendations. Making your dog an outside dog is a terrible idea, it would be better to find a new home for your pup, rather than exposing them to the elements and leaving them outside all alone with no companionship
