When we started asking on our new patient forms, ‘What are your goals for the consult with the dermatologist?’, this became a very common answer. Get to the ‘root’ cause. We wish it were that simple! Dr Painter offers a beautiful explanation here.

What does it even mean to treat the root-cause of a dog's allergies?
I get this comment constantly, especially when I am sharing thoughts on medications. "But that doesn't treat the root cause."
So, let's talk about it.
As much as we all might not want to believe, canine atopic dermatitis is genetic. Heritability has been estimated at 0.47 in Labrador and Golden Retrievers and 0.31 in West Highland White Terriers, and it's polygenic, multiple genes involved.
So if you want to treat the actual root cause, you needed to intervene before the dog was even an embryo. That level of intervention certainly doesn't come in a chew. That ship sailed at conception. Full stop.
But...what we can actually modify is the immune system's response to the specific allergens triggering that predisposition into active disease. That's what allergen-specific immunotherapy does. This is what food interventions do. They doesn't erase the genes, but instead they retrain or settle the immune response those genes are driving. That is root cause work, and it's the only root cause work that currently exists for this category of disease. But, it's not perfect. Because the problem is genetic.
Next time someone tells you that managing inflammation, treating infections, or even immunotherapy "isn't treating the root cause," ask them what they think the root cause actually is, and how they'd propose treating it.
Allergic disease is exploding globally, in humans and in dogs, and this problem is not one created by pharmaceutical companies, or veterinarians who just want to "mask symptoms". Read Allergic: Our Bodies in an Irritated World by Theresa MacPhail if you want to go deeper.
And, before you decide a chew is a root cause therapeutic, or that all medical management is evil, sit with how short-sighted that is. This issue is a genetic, global phenomenon that is affecting us all. The more we open our mind and learn, the better off we - our dogs, you and me - will be. 🐾
