Hi, I have a 3month old male yorkie who is a fluff ball to say the least and I noticed when I was holding him earlier while wearing a white t-shirt that he was shedding & my only question is could it be he's losing his puppy fluff or is this not normal? He is eating well, drinking plenty of water, & just a smart, happy puppy but just wanted to get y'alls input if you have any. Thanks in advance!
