Sometimes our dogs show subtle changes - drinking more, peeing more, or seeming unusually tired - and it can leave us wondering, “Is this serious?” Two endocrine diseases, Cushing’s and Addison’s, can cause these symptoms, but they are very different, and knowing the signs can make a big difference for your dog’s health and comfort.
Cushing’s Disease (Too Much Cortisol):
💠 Gradual changes like increased thirst and urination
💠Appetite may go up
💠Weight changes or a pot-bellied appearance
💠Hair thinning or skin changes
💠Breeds at higher risk: Poodles, Dachshunds, Terriers (Yorkshire, Jack Russell, Westie), Boxers
💠Usually develops slowly and can be managed with medical care
Addison’s Disease (Too Little Cortisol):
💠Can appear suddenly with weakness, vomiting, or diarrhea 🤢
💠Shaking, collapse, or extreme lethargy ⚡
💠Can become an Addisonian crisis, which is life-threatening if not treated promptly
💠Breeds at higher risk: Standard Poodles, Great Danes, Bearded Collies, West Highland White Terriers, Soft Coated Wheaten Terriers
💠Often affects younger to middle-aged dogs, and females slightly more than males
💡 What to remember:
Cushing’s often develops gradually, giving time for diagnosis and management with your veterinarian.
Addison’s can come on quickly, and an Addisonian crisis is a medical emergency. Call or bring your dog in immediately if this happens.
