Not sure my opinion matters, but it looks like there isn't a huge importance the dogs working or getting titles(the ones she uses for breeding).
I do see the brag pages show different accomplishments on the progeny.
Maybe if the breeder would elaborate a bit more on why they are breedworthy I'd be more impressed.
Iknow the lines and background of her dogs. I think she is breeding good German Shepherds from what I can see. They are not for top competition sport people, but 99% of the people who own German Shepherds are not top competition people anyway. Would her dogs do well in family, herding, obedience, and club level Sch....I see nothing there that gives me any red lights. Appears to be good sound breeding from primarily DDR stock.
I saw on their site for some of the dogs that they were prelimmed....if the prelimm is good and available for inspection then this is not concern. Reading hip x-rays isn't some kind of mystical art. More important is looking at overall history of hips then actual dogs involved unless the dogs are moderately dyplastic or worse. Call them and ask about the hips of the dogs you are interested in.
Many folks can't read x-rays well enough to know if they are good or mildly bad. If it were that easy, why even have OFA/ "A" stamp ect... in the first place? If someone is going to be breeding dogs and is going to x-ray them, why not just send them in and get an "official" opinion? That way folks and something to go on other than just the owners opinion of if they are "good" or not.
How are you going to know the "overall history of the hips" if they don't bother to get them evaluated?
I checked their website. Lines or looks?? Which lines and which looks?? Are you looking for long coat or short coat? Bi-color or sable? If you just want DDR lines, there are several breeders who breed DDR. I saw some Czech lines in there too. I am not very good with bloodlines, but some I can recognize.
I don't think it's the DDR that makes them look THAT heavy, I know several DDR lined dogs that are very much athletic looking. Much less "heavier looking", these guys seem to be bred more so for their heavy set structure (not just in weight) more so than anything else, that is just my opinion based on the dogs on the website though.
