only help on food I could suggest is that A lot times its suggested to switch from land to sea then to air. SO if you pet is allergic to lamb or chicken which many are, switch to a food blend that contains fish formulas . If that doesn’t work go to air like turkey duck etc

That’s a big list of allergies. Poor baby needs a portable doggie bubble

I would wash all his new bedding clothes with dreft baby detergent

Im sure you can find plenty of items that are hypoallergenic
