“Lastly, I was told to by the vet to wash him once every month. How come you suggest a weekly bath? Is it to wash off the allergens? Wouldn’t over-washing also get rid of the healthy oils?”
I would go by what your vet advises. He has examined the dog and he is a veterinary healthcare professional.
Without a diagnosis for his skin condition you don’t know what you are treating, medical causes need to be ruled out first. Work closely with your vet, ask for a veterinary dermatologist if you don’t see improvement in a reasonable amount of time.
There are many conditions besides allergies that could cause the symptoms you described.
And again, take a look at pet health insurance before your dog is officially diagnosed, it may be cost effective for you in the long run.
PS: I would definitely go back to Royal Canin if he was doing well on it. Simple 🙂
