Hi I am a newby here and was wondering if anyone had a similar problem or knew of one like this... My son has a Choc Lab that is a bit over a year old. My son recently moved in with his dad while going to College. Dad has a older Black Lab. Choc is male (not fixed) Black is female (fixed). Recently the Choc has started peeing on the black and licking both the blacks pee and his own. My son is freaking out. Has anyone ever heard of something like this? If so what did you do to get him to stop?
