Hi- Unfortunely without the help of a specialist (dermatologist) it’s going to be very hard to determine what the skin issue is and what is causing it. There are a lot of different types of skin conditions from seborrhea to demodex, so you would need to be able to identify what his exact skin condition is through the diagnois of a dermatologist. You can certainly change the food and see if it helps. My dog has symptoms that mimic seborrhea, but it has not been diagnosed as that yet, though I intend to meet with a dermatologist. For the mean time my vet suggested a food for skin support that is fish based. So if your dog will eat fish based foods and you are looking into Orijen and Acana (I’m assuming this based on you saying a food made in Canada), I would try the Six Fish or Pacifica. My dog liked the Six Fish, but did not like Pacifica. Your dog might be different than mine though.
