I've only had my Fido float for a short while so I don't know about the zipper.
I have the tiny and her hair can get caught. But I have pretty much got it down so I don't catch the hair. We have a place called western ranch and pet supply. They only wanted $19.99 and I had a $5.00 off store coupon.
I have another one of those coupons they just put out burning a hole in my pocket destined for a new toy for my girl.
