My 3-4 year old female Am Staff (received from a shelter 5 months ago) has lost her stamina and her coat has changed significantly in the past (2) weeks with general hair loss below the neckline. The first indications that she was tired occurred approximately (3-4) weeks ago but she will still initiate play and wants to walk- just breathes harder and needs to take breaks which begin early in the activity. In the past (1-2) weeks her black coat lost its sheen and looks dull and gray. Some spots appear to be darker and wet looking but the size and shape of the spots lack consistency throughout her body. Overall, she is shedding a lot Her head, ears, and lower legs are not affected. She is eating/drinking and eliminating as usual.
The Vet scrapped several areas down to the skin to examine and ran blood tests for parasites and thryoid which came back negative. Now they want to sedate her and do biopsies of the skin. We've been fortunate with our other dogs and have never had to go through testing like this. Does anyone know what this could be or if we should be doing something else for her? Any advice would be appreciated. Thanks!
