My dogs have been rather itchy lately, to the point where one of them has scratched herself so much and now has a nice little scab on her face. These dogs are inside dogs and rarely go outside so I don't normally use any sort of external parasite preventative as I'm a little skeptical about putting an insecticide directly on my dogs. Anyway, I've thoroughly checked them and I see no fleas or ticks so I was thinking that perhaps they have some sort of lice. If they do have lice, I would imagine they got it from the feeders I bring home. So my question is do any of you dog owners do something to the feeders you bring in to your house so as to avoid cross contaminating your pets? I'm sure spraying the feeder bin with PAM would help, but idk how feeders + PAM + snakes would turn out.

Any advice would be greatly appreciated.
