I started experiencing the same thing with my intact female. Her hair loss coincided with her first heat. Her diet has been the same since I got her at 10 weeks. There was no sign of fleas, and she was not scratching or chewing. Her skin looked fine to me, but after 3 weeks we went to the vet. He was unable to determine an immediate cause, even checking her skin under a black light for any signs of a fungus, and since it coincided with her heat cycle, he felt it may be hormone related.
His philosophy is to keep it simple, so he prescribed 3mg Melatonin twice a day. He has successfully treated another Yorkie in the practice with this treatment and since it would do no harm other than possibly making her a little more sleepy, and it being a very economical approach. He said give it 2 months and if there is no improvement he would pursue other avenues. She has been on it for a month and I do see improvement.
I hope this helps! |
