They experience a slow healing process

If your beloved furry friend already suffers from another disease, stress can slow the healing process because of cortisol. Cortisol – the hormone of stress – not only affects their immune system but also slows down the healing process. In this case, animal experts avoid using corticosteroids – meds that have the same effects as cortisol in the body. 

“Cortisol has an anti-healing effect,” Werber said. “That’s why we try not to use corticosteroids because they slow down the healing process; cortisol affects our ability to fight disease.”

So, try to find their stressors and call your vet for more information, help and treatment, especially if your pet is already sick. Try to pay attention to their behavior and tell your vet what you discovered.
