5 Reasons Why I Now Recommend Liquid Collagen To All My Patients With Allergies
Dr. Katherine Mercer, VMD | Board-Certified Veterinary Dermatologist | 20+ Years Experience

For 20 years, I prescribed what I was taught. Apoquel. Cytopoint. Prescription diets.
And for 20 years, I watched the same pattern — it works, then it stops, then we increase the dose, then we add another medication. I was managing allergies. I wasn't fixing them. Then I discovered something that changed how I treat every allergy patient that walks into my clinic.
Here are the 5 reasons I now recommend liquid collagen first — before Apoquel, before Cytopoint, before anything else.
1. It Rebuilds The Barrier — Not Just Suppresses Symptoms
Your dog's skin has a protective barrier made of collagen. It keeps allergens out.
After age 2, dogs lose this barrier. Gaps form. Allergens flood through. The immune system panics.
That's the scratching. The hot spots. The ear infections.
Apoquel suppresses the immune response. Cytopoint blocks the itch signal. Neither rebuilds the barrier.
Collagen does. That's why the results last.
2. It Works With The Body, Not Against It
Apoquel suppresses your dog's immune system. That's how it works. But long-term immune suppression comes with trade-offs.
Collagen isn't a drug. It's the natural protein your dog's skin is made of.
No suppression. No side effects. Just repair.
3. Liquid Absorbs At 98% — Pills Don't Work
Dogs only absorb 20-30% from pills and chews. The rest passes straight through.
That's why those Amazon supplements did nothing.
Liquid collagen absorbs at 98%. It actually gets into the system.
If you've tried collagen before and it failed — this is why.
4. 50,000+ Pet Parents Have Found The Relief They Thought Was Impossible
Over 50,000 pet parents use Healthy Petz Liquid Collagen daily. Their dogs had been struggling for years.

Until they found real relief: Scratching stopped. Ears stayed clear. Paws healed. Hot spots gone. Coats growing back thick and healthy.
Different symptoms. Same solution. The barrier rebuilt.
