Warning: This post discusses poop. Specifically dog poop.

The dog’s poop is marbled with blood. (I told you.) He relieved himself on the basement’s honey-hued carpet, which now bears permanent crimson splotches, some of them in the shape of small nations and rural flyover states. It’s a fecal atlas. 

Flippancy aside, recall: poo, blood, dog. This is eyebrow-raising on one hand, panic-time on the other. Bloody dookie is nothing to snicker, or snarl, at. It’s a call-the-vet-pronto affair, especially when said doggie, Cubby, is also behaving strangely and doing this regurgitation thing in which he chews and swallows whatever he’s just hacked up. It’s coming from both ends. It’s abnormal. We fear for the furball.

Should I worry if my dog’s stool has blood or mucus? That’s an actual question posted at Pet Health Network, a, well, pet health network that will either assuage your nerves or trigger the trots. 

If you, like me, are a hypochondriac, then you shouldn’t even be visiting sites like this or the human version, WebMD, where I often go to learn that my tennis elbow is likely an inoperable tumor and my heartburn is assuredly a minor stroke.

(Doctors hate sites like WebMD for spawning a nation of needlessly freaked out patients. I used to carry a sheaf of so-called diagnoses that I printed from the internet when I visited my doctor. He wanted to strangle me.)

The answer to the “my dog’s stool” query has several answers, making for something of a rollercoaster ride. Causes might be: an upset stomach from eating bad food (whew); inflammation of the colon (also, probably, whew); internal parasites (some antibiotics and we’re good, right?); cancer (Jesus!); allergies (we can deal); autoimmune disorders (egads). 

Cubby the über-hound is at the vet as I type. (No matter the diagnosis, I won’t let him read this.) The sun is dipping, kicking up skies of charcoal and embers. It’s 35-degrees out, just right, and somebody has to clean up the basement carpet. If Cubby’s OK, he can do it. 

And now a text arrives from Cubby’s mom at the vet: The doc can’t tell what the problem is but the bill, counting all manner of exams, including a stomach X-ray, is a soul-shriveling $901. Almost a thousand dollars in less than an hour. I’m gobsmacked until I remember how I once spent roughly $500 on an ailing pet rat. Animals will do that — break your heart while breaking the bank.

So it appears to be wait and see for schlubby Cubby, despite the red-streaked poop, which is actually the least of the vet’s concerns. The dog has a fever of 103, says the vet, who gave Cubs an antibiotic, anti-nausea meds and fluids for dehydration. The tummy X-ray was sent to a specialist, even though the vet saw nothing unusual in it like, say, a toothbrush or an iPhone.

This non-vet will tell you the animal has been unusually lethargic, and has picked up some odd habits over the days (he’s suddenly fond of karaoke and mojitos) and has dramatically altered his cravings (he wants nachos and Popeye’s). He isn’t chewing his beloved bully stick, which is, literally, a dried bull penis. He canceled his subscription to People and has gone to watching the dreadful third season of “True Detective.”

He’s one sick pup.
