To those of you wondering if pyrs shed much, the answer is an unequivocal "yes".
At about a year and a half old, Abby is going through her first summer and loosing her puppy coat in a big way. It's getting to the point where I'm making more progress pulling out the undercoat by hand than I am by brushing it out. Can't wait until it's all out and we can just deal with the usual level of shedding!
