Oh wow, that is a pretty low SDMA. It is not even close to the high end.

Should I be worried? His vet seems to be and wants to do a urinalysis

With those levels, I would say that is it very highly unlikely that the cause of the elevated BUN and Creatine is related to the kidneys.

I am not very worried, but was getting ready to type, that you could do a urinalysis to ensure that the kidney are functioning normally.

If he ate a high protein meal prior to blood work would that cause the levels to be elevated

Most likely the urinalysis (at least the stuff related to kidney function) will be normal with such a low SDMA. However, a urinalysis is not a bad idea. I normally run them as part of my senior panel in my geriatric patients.

You are absolutely correct that a high protein meal prior to bloodwork could cause that degree of elevation.

Ok that’s a relief. What else would cause the levels to be elevated other than dehydration or high protein meal?

Also, a bit of dehydration could cause that. So if he was maybe panting and didn't get to drink water while he was at the vet, that could explain it too.

On other possible cause of an elevated BUN with normal kidney function is a bleeding stomach ulcer.

Normally with that the BUN goes up a bit and the creatinine is normal.

Also, we usually see changes in appetite, but not all dogs are nice enough to let us know something is going on.

Stomach ulcers are most common in dogs that are on daily NSIADs such as Rimadyl

He definitely has no changes in appetite. He's not on any NSIADs

Since he is on the high protein diet, I would recommend that you ensure that he has been fasted for at least 12 hours prior to any future blood draws.

Ok. Shouldn't his vet be advising me abt this? Seems like it's common practice

We usually don't require fasting, but it is not very common that it makes a difference in our values, but I occasionally will have a patients that it seems to matter with.

Oh ok. It would have been nice if the vet had ask if Muji ate prior to the blood work.Thank your for answering my questions and easing my stress

I understand. I do think this is an aspect that we vets could improve upon. I know in human medicine they are militant about fasting for cholesterol purposes. We should be better about suggesting it in veterinary medicine since there is the occasional case that it matters.
