I would honestly run from any breeder who touts the WEIGHT rather than the size of a dog. There are many breeders who produce oversized dogs, which they often claim are "true, old-fashioned" Shepherds, and who will tell you all about the dogs' weight. Looking at photos, many of those dogs are just FAT in addition to being over the breed standard in size.

If you like a larger dogs, there are some reputable breeders whose lines tend to produce dogs that are slightly over the standard in height. For Shepherd, the standard calls for females to be no taller than 24" and males 26", which makes them a Medium dog breed, actually, not a Large dog breed. (Although I guess your definition of Large would depend on comparisons.)

Not at all "normal" for a properly bred GSD to weigh over 100lbs.
