Have you ever noticed your cat grooming so much that bald patches appear, or your dog restlessly pacing around the house? What may seem like small quirks can actually be signs of emotional distress—and over time, they may quietly weaken your pet’s immune system and overall health.

This article explores the powerful connection between emotion, immunity, and disease—and why supporting your pet’s emotional well-being is just as vital as caring for their physical health.
