These are her housemates. A male Rhodesian Ridgeback named Xindika on the left and a female Greyhound named Nellie on the right. Sorry I didn't get more pics, I was trying to not be that annoying person with the camera. (I was at a going away party.)
Birdie has NO pink spot on her belly. It is completely covered with fur.
Now I have seen alot of dogs. Between working at a vets office and the 100's of shelter dogs over the years I have never run across this before. It made me curious. Has anyone seen this before or have any thoughts?
