Please listen to your vet and start the prescription food right away and whatever other recommendations the vet has made. Provide plenty of fresh water and frequent bathroom breaks. I would get the kibble plus the canned version, mix and add a little water (measured amounts 2 or 3 times a day) no free feeding.
Believe me, you want to keep kidney disease at bay. It’s good that your vet caught this early. It’s not unusual for a senior dog to have labs that are a little off, but hopefully with the special diet you will see improvement when you retest in a few months.
I’ll never understand why people disregard the advise of their vets. The internet is not “research”. There is a lot of incorrect information on the internet.
I hope that you will pick up the prescription food today and ask your vet to explain the rationale for the special diet and anything else that you should be doing.
Btw: Raw is the worst thing you could feed a dog with kidney disease.
