I am concerned that Marley is uncontrollable thirsty and is losing weight. He could have an infection, kidney disease, liver disease, diabetes, etc. so he should be examined by a vet to determine the cause. Your vet can run a urinalysis and blood work to help diagnose and treat the problem. Please call your vet and schedule an appointment.
