Pet's info: Dog | Shiba Inu | Male | neutered | 28.8 lbs
My dog got diagnosed with kidney disease. His BUN levels are normal but his creatinine levels were elevated and so were his SDMA. It seems like it has been caught early on. They want him on a low sodium diet. What can he eat and not eat? He's very food motivated. Can he do all his everyday activities such as the dog park? I'm terrified of watching him deteriorate. He's almost 4 years old.

If you are suspicious that your dog may be developing kidney disease starting him on a renal diet is a good idea. By having lower salt, proteins, etc, the diet will be putting less stress on the kidneys and this will hopefully help them to function better and for longer. It is also helpful to start them on a kidney diet earlier rather than later because by the time they have notable kidney disease they don’t want to eat as well and it makes switching foods more difficult.
As I’m sure your vet explained, kidney values do not start elevating until about 60-75% of all kidney function is compromised. This can make it difficult to determine early stages of the disease.
There is a newer test to look for decreased kidney function called SDMA that can detect kidney disease earlier than traditional tests. You may consider asking your vet about this test if it has not already been performed.
I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck!
