Why is my 7-year-old dog drinking lots, sleeping, and not playing?
Hello, and thank you for your question. Increased drinking and lethargy can be due to kidney disease, liver disease, pancreatitis, or thyroid disease, among other possibilities. I would definitely get Buddy checked out by a vet. They will likely recommend blood work and urine testing, which will help to differentiate between the above possibilities. Many of these diseases are easily treated through a combination of medication, supplements, and diet changes, and can offer a continued quality of life for many more years.
I hope this helps, and that Buddy feels better soon.
