Why Probiotics, Chews and Elimination Diets Didn't Stop Our Dog's Itching

When I first noticed that our dog seemed to be scratching herself a lot more than other pups did, I did what any sensible owner does: I consulted the internet. I was looking for causes and, of course, potential solutions.

And what I found was a lot of discussion around gut health. “Fixing the root cause” was a popular refrain. Along with “balancing the gut microbe." I got sucked in, and I bought the chews that kept showing up in my Instagram feed. Nothing changed. I read in a Facebook group that many dogs are allergic to chicken, so we got rid of her favorite chicken treats :( She was still itchy. Same with peanut butter.

Different (and expensive) probiotics were procured and mixed with her food. Nothing changed.

The itching, the paw chewing, the constant licking and the red staining from yeast overgrowth seemed to be getting worse.

The turning point came when we finally got her in front of a canine dermatologist and did a proper skin allergy test. The results were overwhelming: Lainey is highly allergic to weeds, grasses, certain trees, insects, dust, dander, feathers, cats… and yeast. Environmental allergies. Not food. That's when the dermatologist said something that changed everything for us: 

“Dogs aren’t like humans. They absorb things through the skin.”

All those months of restricted diets and gut-focused supplements hadn’t been addressing the actual problem. The allergens were sitting on her coat and paws and absorbing straight through her compromised skin barrier. No amount of probiotics was going to stop that.

This is the expensive, exhausting myth that traps so many of us: We assume chronic itching = food allergy or gut imbalance, because that’s what we hear the most often. It feels actionable. You can control what goes in the bowl.

So we spend a lot of money on special diets, supplements, and elimination trials while the real culprit environmental allergens on the skin doesn’t get addressed.

I’m not saying food allergies don’t exist. They do, and they’re worth ruling out. But for a huge percentage of dogs with year-round itching, paw chewing, and recurrent yeast issues, the problem is environmental. And until you understand that the skin is the primary entry point, you’re fighting the wrong battle.

Once we accepted this, everything shifted. We stopped the internal war and started protecting her skin from the outside. Frequent, gentle bathing became the foundation of her management, not because it’s a miracle cure, but because it removes the allergens before they have a chance to absorb. It’s simple. It’s more work than I would l like it to be. And for dogs like Lainey, it can make a real difference.

That realization is why All Good Wash exists.

If any of this sounds familiar, what have you tried for your dog’s itching that didn’t work?
