Our dog's been diagnosed with Cushing's Disease, where the pituiary gland secretes too much hormone. We don't have pet insurance. She was drinking like a fish, peeing everywhere and ravenous appetite. Humans can get it too but it's rarer than in dogs. She's to be on tablets for the rest of her life and is 11. They're £96 for 30 and vet's now prescribing 180 for 6 months so almost £600. May get them cheaper online but am a bit reluctant to buy medication from the Net.
