I Have a GLWP and he has a tendancy to loose his fur. He did it when he was slightly younger and I had him at the vet they took skin scraps etc and blood test and evrything came back negative Suprise suprise!!!!. His fur then grew back on its own. Then about 3 months ago he lost the fur of the top of his ears. I cant seem to find out whats wrong with him. He is very healthy and happy with everything in life. Hes a cracking tracker, its just he looks a bugger with no fur on his ears. Van anyone give any feed back or advise.
