Nope, it was my very first yorkie that had kidney disease. We lost him 16 months ago. But, he lived to be over 16 years old and battled kidney failure and chronic pancreatitis for the last 3+ years of his life.
My female is a little toy poodle. They have longer legs than yorkies, so maybe that's why the soup ladle slides right under her.
After what I went through with my Scooby and his kidneys, I'm pretty anal about keeping a close watch on the rest of my dog's kidneys. They have blood work at least every year and it now includes the SDMA test, and I do a urinalysis yearly as well. I know BUN can vary based on diet, and there can also be slight variations in crea based on diet but I've not heard that about the SDMA. Good question to ask my vet though. Thanks for bringing it up.
Good luck catching that sample!
