I've noticed lately that Franklin has been itchy. He scratches his ear and jaw, mainly. No bad smells or gunk coming from the ears. I've looked for fleas but I don't think it's fleas because Maggie isn't scratching and Franklin isn't really scratching his body. I thought at first it might be dry skin so we put a humidifier in the living room, but it's only been a day or two so I haven't seen any real results.

I'm starting to lean towards an allergy. I took him off chicken because I thought a food allergy was the issue. Now we're on fish and he's still scratching. He also has a lot of eye gunk. Maybe it's something environmental?

Any suggestion as to what to do?

ETA: I forgot to mention the foods we've been on. We started off on California Natural Puppy (Lamb and Rice). He started to get bored with the food so we switched to Solid Gold Hundchen Floceken (Lamb). Their poops were awful with that so we switched to Wellness CORE. First they were on the Original formula but I started to notice itching so I thought the chicken was bothering him. Now we're on Wellness CORE Ocean. I'm planning on switching to Nature's Variety Instinct (Turkey/Duck or Rabbit) after this bag is done.
