Why You Shouldn’t Give Licorice to Dogs with Cushing’s Disease

Cushing’s disease, also known as hyperadrenocorticism, affects a dog’s ability to produce normal levels of natural steroid hormones like cortisol. Many pet owners have looked on helplessly while their beloved pet suffered from a host of distressing symptoms: from excessive thirst and urination, to increased appetite, hair loss, thinning skin, panting and fatigue. The pain and heartache of watching your furry friend go through this without relief raises one question: how can I help? Conventional treatments are available but can be costly and often have a host of negative side effects. This leads many to seek out alternative therapies that work with the body to restore balance rather than just suppress symptoms. Fortunately herbs and nutraceuticals that can help.

For this reason it’s generally best to use trusted formulas that do not contain licorice.
