Tyler was a four-year-old golden retriever.
His owner had been through the full protocol: two rounds of Apoquel, one Cytopoint shot, three prescription foods, five medicated shampoos, dewormers every three months, and a referral to a specialist.
Total cost: about $4,200 over 18 months.
Here's what I saw when Tyler first came in:
β
Scooting several times a day
β
Paw licking so bad the fur was gone from both front paws
β
Hot spots that kept coming back on his sides
β
A dull, brittle coat that was shedding heavily
β
Loose stool three or four times a week
β
Restless nights β pacing, sighing, unable to settle
Every fecal test came back clean. Every allergy panel was mixed. His blood work was fine.
On paper, Tyler was a perfectly healthy dog.
But he was miserable.
I did something most vets don't do. I ran a PCR-based parasite panel β a test that looks for parasite DNA instead of counting eggs under a microscope. And I ran a gut permeability test to check for what's called "leaky gut."
Both came back positive. Strongly positive.
Tyler had a low-level parasite load his fecal tests had been missing for a year and a half. And the inflammation from that load had broken through his gut wall β which is why every "allergy" treatment kept failing. His immune system wasn't overreacting to pollen or chicken. It was reacting to a real threat that nobody had thought to look for.
That's when I stopped treating skin as skin. And it changed my practice.
