My yorkie is almost 2 years old and lately i've noticed two things he has been really whinny and ive started to find clumps of hair everywhere. I dont know what to do to help him. I've always kept his hair very short and a few months ago i decided to let it grow all the way out, so my first guess was that maybe he doesnt like it long. and as for the whining i dont know whats wrong. I've made an appointment with the vet today so hopefully we can figure this out. Is this normal behavior for a yorkie?
