Hi, thanks for using Petco Pet Education Center, formerly Petcoach! The most common reason for the fur to be that color is from excessive licking. There is a pigment in dog saliva that stains the fur reddish brown. As for her urine being brown or red, that is not normal. I would collect a urine sample and have her seen by your Vet tomorrow. The most common reason for red-brown urine is blood. Bloody urine can be from a UTI. The Vet can diagnose an UTI from a urine sample and also address her excessive licking (allergies, skin infection or fleas are common causes). I wish Harlow the best!
