Why so much red dye??

These pug ears were great, they took my mastiff a while to get threw. My only quark with them and it's a big one, is there is soooooo much red dye in them. By the time he was done with them my carpet was dyed radish brown. And I know the dye can't be that great for him if there's that much in them. One request....can you do these without the dye? I'm not concerned about what they look like and neither is he if they are quality products.
