Hi, I was just wondering if there was some sort of chart or something that can tell you the average Sheltie birth weight. And how the average weight should be as they progress, so you can tell if its a rather small pup or a rather large pup. I am not a breeder or anything just wanna learn a lot more about Sheltie breeding because when I get older I want to become breeder and agility and possibly show them. Or maybe all. And if you guys have any other personal experience with basically anything about breeding, whelping, weaning, puppy care ect. I think that I have possibly read everything about breeding but you can never learn too much. Ohh and I'm only 15 but I love Shelties with a passion and know that they will always be in my life, so I wanna learn as much as I can. Thank you guys!
