ATTENTION! Age related problem
My dog Shadow passed away a few days ago with High Kidney Urea... This happens due to old age as the kidney's start to weaken. It causes ulcers throughout the digestive track due to the high urea. Dog's usually have blood urea ranging from 1 to 45 but before his death it was 704 which was too high... Since it is a kidney problem there are no visible symptoms and it could even be rising without your dog showing any difference until it gets out of hand ... thus, blood tests every 6 months are recommended for dogs over 8 years of age and more often than that is you have spare time.
I just thought i would mention this because i don't want people to lose their dogs to a problem that is age related and easily curable if caught early on by regular blood tests since there are no visible symptoms early on ..
