i have a four year old spayed female brown lab x pointer x setter. I got her at a pound when she was 10 months old and spayed already. She has been the best dog i've ever encountered (no really...not being biased... she is incredibly smart and loving) Ever since i've had her (from day 1) she has NEVER had an accident in the house besides vomiting or diarrhea. Just recently, she peed on my bed and acted very guilty as i was smelling it trying to figure out what it was in disbelief. I was gone at work while she did it, but my two roommates were home to let her out all day. I was dumbfounded and shocked. Two weeks later i was gone for four days while she was in my roommates and girlfriend's care. It turns out that right after my girlfriend had walked her she peed on my roommates bed in the same exact spot, but different bed. Once again i had no idea to make of it. Was she trying to get back at me for being gone? I have been away many of times with her in great care with no incident. Now, two weeks later from bed pee #2, i come home from class, to find that she has peed on a futon!!! All different beds!!??? She goes skiing with me and plays frisbee every day!? She is out side in a fenced yard all the time, when ever she wants! what is going on? please help i don’t know what to do. She is never neglected or unloved, what is going on?
