Did Your Dog Ever Grow a Toe Out of Its Chest?

WARNING: There will be blood. Not a lot, but some.
You and I are no strangers to the internet. We get how all this works. Lots of insanity balanced by little doses of reality.
Still, there are times when something can catch you off guard and make you gasp as you utter, “WTAF?!?”
For me, it's almost always in response to a story shared by a shelter about how a dog came to be in their care. There are some real doozies out there.
Sometimes, though, it's something small.
And even though it's small, it can just make you stop what you're doing, gaze off into space for a while, and ponder what it is that you just saw.
This is one of those times.
"Crazy question… has your dog ever grown a toe out of their chest…. Did it randomly fall off after a bath… inquiring minds and all that lol"
I mean, how do you even process that?
Is this real life?
Apparently it is.
And if David After Dentist taught us anything, it's that sometimes the only appropriate response to reality is to stare into the middle distance and question everything.
Meet the Mystery Chest Toe
This particular mystery came courtesy of a dog lover who asked the question in a Facebook group I happen to belong to.
And, thankfully, there were photographs.
Because without photographs, I would be asking you to take my word for the fact that someone had apparently discovered a tiny, detached appendage on their dog's chest.
With photographs, however, we can all stare at it together.
And I have to say ...
It really does look like a tiny claw.
The growth was attached to the dog's chest and had a distinctly hard, claw-like appearance.
Then came bath time.
And afterward?
The mystery object had apparently detached.
Which leaves us with several very important questions.
What was it?
How did it get there?
And, perhaps most importantly...
Why does this dog appear to have been issued a bonus toe in the middle of its chest?!?
So... Can Dogs Actually Grow Things That Look Like Toes?
Well, yes.
Not toes, exactly. But dogs can develop some remarkably weird-looking skin growths.
One possibility for a projection like this is a cutaneous horn — a growth made primarily of excess keratin that sticks up from the surface of the skin. Keratin is the tough protein that makes up things like hair and the outer portions of nails. Cutaneous horns have been documented in dogs, although they are considered uncommon.
And there's an important distinction here:
“Cutaneous horn” describes what a growth looks like. It doesn't necessarily tell us what caused it.
Veterinary sources describe several different skin and hair-follicle lesions that can produce a horn-like, cornified projection. For example, canine cornifying epitheliomas are benign growths that can stick up from the skin and look rather impressively horn-like. Keratinized skin cysts can also produce very strange-looking material.
In other words, there isn't a tiny veterinary filing cabinet labeled "CHEST TOE" that allows us to pull out the appropriate diagnosis.
Which is probably for the best, really.
But What About the Fact That It Fell Off?
That's the part that really makes this story interesting.
Some dogs will traumatize or scratch at certain keratinized growths, which can cause them to rupture or become injured. According to the Merck Veterinary Manual — a long-standing, widely used reference for veterinary professionals and pet owners — dogs with cornifying epitheliomas may scratch, rub, or bite at them, which can lead to trauma and possible secondary infection.
But we can't look at these photographs and say with certainty that this particular growth was a cutaneous horn, a cornifying epithelioma, a cyst, or something else entirely.
And that's actually an important lesson.
The internet is really good at helping us recognize that something is weird.
It is considerably less good at telling us exactly why something is weird.
What Should You Do If Your Dog Grows Something Weird?
First, try not to panic.
Your dog probably hasn't spontaneously begun the process of evolving into a woodland creature.
But don't ignore it, either.
If you notice a new growth, lump, bump, lesion, or mysterious horn-like object on your dog:
Take a picture.
Get a good look at where it came from.
If something has detached, save it in a clean container or bag and ask your veterinarian whether they want to see it.
And let your veterinarian know about the growth — particularly if it comes back, changes, bleeds, becomes irritated, or seems to bother your dog.
Some unusual-looking growths are benign. Others can have different underlying causes, and appearance alone isn't enough to tell us which is which. In some cases, a veterinarian may recommend sampling or removing a lesion so it can be examined more closely.
And Now You Know About Chest Toes
Do I know exactly what this particular dog grew? No.
Do I know that it was a very convincing imitation of a tiny dog toe? Absolutely.
And I'm grateful to the dog's human for giving me permission to share these photographs, because otherwise I would have had to explain this entire story without the visual evidence.
And honestly, I'm not sure you'd have believed me.
So the next time you're giving your dog a bath and discover something that makes you stop, stare, and wonder whether your dog has quietly developed a new body part ...
Take a picture.
Call your vet.
And then, if you're anything like me, stand there for a minute and think:
“WTAF?”
Because apparently, sometimes dogs grow things.
And sometimes those things fall off in the bathtub.
Dogs are weird.
And I wouldn't have it any other way.
