I am so sorry It is sad that her condition was not caught sooner. How long ago was that?Oh yea MJ had very very pink skin and was always getting sun burnt. She also had a problem with hot spots too. We never knew until it was too late but she was born with an extra flap of skin inside her nose that made it very hard for her to breath right. We lost her at a very young age due to a heat stroke. If we only knew what we know now we may have been able to save her or at least had her with us a little longer.
I think most skin problems arise in dogs like this because of lack of pigment in the skin.
