I eventually switched Newton from Pettabs to a bunch of goodies, including some cheweable pills (Vetriscience's Canine Plus and Cosequin), B-complex and an antioxidant capsule. He is not very fond of them. I suspect there is more yummy filler in Pettabs than in those pills, but unfortunately less of the ingredients that I am interested in.
I tried to immerse the pills with fish oil, and early on it worked, but no longer. And the antioxidant capsule is a total no-no. I have to fight him twice a day. I wrap the goodies in melted cheese, but often he would eat the cheese and spit the pills out. Very picky boy 
I am thinking of trying to grind the pills with freeze dried liver. Any other trick that I should know?
