I have tried everything with my 7mo old puppy and I can't seem to get her to eat. She will just nibble at her food,tried every food out there grain free to raw to home cooked. She goes through these spells that she doesn't want to eat so I have to feed baby food through syringe. Vet doesn't understand it and every time she drops weight.

Perhaps it may be time to gather your records and seek a second opinion.

This is hard to help you, Im going to ask you what cleaning products you are using, or possibly hair spray. Dogs spend most of their lives under are feet, which means that anything that your spraying into the air the dog is inhaling. Febreeze an any cleaners that contain that ingreident are harmful to are pets so try to use another cleaning product an don't use fabric softners of harsh detergents like one that has four letters an begins with a G when washing their bedding. I cannot use G. detergent, I break out horribly an most things don't bother me. Hope you take a close look at what you are using an you may find your answer. What I said about Febreeze has been documented as true. God Bless
