Yeah. That's dogs for you. I don't think they do it to disguise their own scent, I think they do it because they downright LOVE it! I mean, you can tell they love it. You want to please a dog? Wrap up some fresh shit or week-old roadkill for him and give it to him on his birthday. Dogs are filthy by nature, and they love it.

Anyway, there's no point disguising a fairly mild bad smell with a bad smell that is so strong that it could melt a brick wall...

What is the dog's prospective prey going to think? "Hmmm. There appears to be a bunch of shit and decaying bodies coming this way. Hmmm. Gee. I wonder how that could be? Should I be concerned about this? Hmmm...."
