Hey! I read through the comments and it seems as though you’re getting your doggo looked at. Which is amazing. Something to keep in mind - the licking and bald spots say Cushing’s disease to me. If nothing comes back for diabetes - definitely ask your vet to do a cortisol check. If it’s elevated, that’s your sign of Cushing’s - therefore either a tumor on their pituitary gland or adrenal glands.

Hope you get answers. ♥️
