9 year old FEMALE DOG (?) always hungry and thirsty,any cure?

My spaniel has developed a great hunger and thirst recently,she has been to the Vet,no kidney problems,in good health and very active still,suffers from “leakage” also,any ideas on how to control these symptoms with natural products?,I am reluctant to try a lot of pills that may be prescribed and not work.
Yes diabetis and worms checked

Is your dog on a good quality food? When did you have her to the vet? Did he do a urine test for diabetes, or the one that is repeated each hour? Call your vet and have her rechecked if she is still very thirsty and hungry. If your vet cannot find a reason, ask him for a referral to a specialist. taking pills for something you don’t know the cause of is never a good idea. Please continue to consult veterinary professionals. Good luck.
