I just read that they're training dogs to detect bladder cancer in humans by smelling their urine.

Now, I don't think this is such a big breakthrough for the MEDICAL industry. After all, they have machines that can detect bladder cancer too, I suspect.

But I think this is a huge breakthrough for the DOGS.

Because now dogs have an excuse to smell people's crotches.

Isn't that all they ever really wanted?

And if people get mad at them, they can just be like, "Hey, I'm just doing my part for MEDICAL SCIENCE. "

(This last part of the joke is, I suppose, dependent on dogs talking. Which mostly they don't. But I will not let that stop me. If I have to train dogs to talk to make this joke funny, by golly I'll do it.)
