I would be astounded if your
"Our shepherd got "wandering lameness" at 5 months, he went down, was completely lame, would not eat, was dehydrated."
had ANY relevance to a question about HD - it sounds to me like Panosteitis, the human version of which is known as "growing pains".

"rahul a":
Back in the late '60s, before my country had an xray scheme, I produced my first litter. And a couple of pups were collapsing in pain at 3-4 months old. As a result, I went to our veterinary university where they were testing out ways to diagnose HD, then researched & learned a lot! By the way, my bit.ch proved that their physical tests were useless - she was sound (she'd been a placegetter at my country's equivalent of Crufts & Westminster), accepted weight, and happily waltzed with the profs. But xrays showed that she had effectively no hips, despite that she had leaped 7-8 feet vertically from her pen to come inside through an open window while we were shopping, opened the fridge, ate her meat for the next 3 nights, and topped it off with a dozen eggs - and then had the cheek that evening to tell us that she WOULD like her dinner now, please!
The last litter in which I produced a dysplastic was born in 1983 - and it wasn't my idea, it was a "surprise gift" from a pup allowed to run unsupervised with his on-heat dam because he was too small to reach her "target" and anyway he was too young to be fertile. Yeah, right.....
In other words, how common HD is in a particular kennel depends on the intelligence of the kennel's owner, particularly how he/she uses the xray evidence available. Although a veterinary university in Hamburg claimed at the end of March to have identified one the DNA sequences responsible for HD, for a while yet we will have to rely on xray schemes.
Unfortunately for Yanks, the only xray schemes in their country are the two worst. The OFA scheme tells breeders almost nothing until it is too late. I'm not surprised that "Chetco" reports little improvement from using the OFA scheme. And few experts accept the basic premise of PennHIP - yes, all pooches with HD have loose joints, but not all pooches with loose joints have HD.
"Nancy M" is obviously one of the thousands of dog owners who doesn't understand that hip dysplasia and elbow dysplasia are the expression of RECESSIVE alleles, albeit modified by the environmental factors of diet & weight & fitness (or lack of) & type of activity - blame the way OFA is promoted, and blame the lack of information on its useless reports. Especially blame the lack of progeny analyses!
A dog's OWN xray tells you only whether it personally displays the effects of HD (or ED). It tells you nothing about how many of the dysplasia recessives the pooch possesses, each blocked in that dog by its "good" dominant allele. Until DNA matching is available, breeders need to check the hips of the parents & siblings and grandparents of both the new stud & new brood they are considering using - and, if possible, uncles and aunts as well. After the stud has had several litters, a more reliable guide is a progeny analysis.
● The best scheme - the BIF-scoring used in Britain, Australia & New Zealand - reports on 18 aspects of the hips, scoring EACH ASPECT from 0 to 6 (actually, one aspect per hip is scored from 0 to 5), so that breeders can tell whether any aspect is close to being a concern and take appropriate steps; that gives a total scale of 0 to 106, as against OFA's 6 categories. And it publishes a progeny analysis every year. When the scheme was first set up (by GSD people in 1978 but not adopted for all breeds in Britain until 1983, not by my country's NZVA until January 1986), the breed's average was 18-20. In Australia that has come down to 14±, in my country it has come down to 11±.
● The other useful scheme is the German SV's ZW scheme. It uses a computer to every 3 months factor in a host of close relatives' hip results; the ZW produced is like an IQ, but in the opposite direction - 100 is still "average", but the lower the ZW the better.
I hope your pup is from a rescue group. That is a valid reason for having no access to information about the parents. No-one should encourage puppy millers and ignorant BYBs by getting a puppy from them or from their agents, the pet shops.
Basically, now that you HAVE your pup it is too late to worry about HD or ED or Pano, unless you are prepared to return the pup to where you got it and start again, this time the right way.
If your pup is destined to develop a joint dysplasia it WILL develop it. But there are things you can do to minimise the speed & degree that it takes effect - and they are good things to do even if your pup isn't destined to develop a dysplasia.
(1) Keep it light in weight from now on. If your pup has the correct GSD coat, soon after 5 months old you should see every rib outlined by the muscles working over it while the dog gaits or pants, but never more than the edge of the last rib when it is rested - the GSD should be in the same condition as a human who is a champion marathon runner.
(2) Feed raw meat on small bones (skinned rabbits, chunks from lambs or young deer) - meat is the basic diet of carnivores; the gnawing exercises the cheek muscles that control their ears, clean the teeth, help dislodge the deciduous teeth, and help the permanent teeth break through the gums, and any bits that get digested contain the perfect calcium:phosphorus balance. Supplement that with cooked table scraps or dog bix a few times a week.
(3a) Allow the pup freedom to exercise whenever it wants - lying in a crate doesn't develop muscle (nor does it develop intelligence & self-confidence). When a pooch cannot have the run of the house it should be in a roofed escape-proof run outside where it can experience the sounds & smells & movements of the environment or snooze in a raised box or bounce from end to end of the run and go toilet whenever it wants to.
(3b) Avoid high impact exercise; avoid exhausting exercise - exhausting for the pup, not for you.
The condition of the muscles & ligaments is crucial - they have to be tight, to hold the bones in the correct relationship to each other so that the knobs and sockets and balls all work properly.
I'm not sure when agility dogs are allowed to start jumps and scales, but SchutzHund dogs aren't allowed to start the high-physical-stress activities before 15 months old - they are far from mature then, but have enough muscle to start the actvities, albeit at easier levels than "the real thing"..
Ignore "advice" to "prelim" your pup.
Less than 16% of HD is detected by xrays taken at or before 6 months old!
By 12-13 months old 70% gets detected, and only OFA deems that too young to certify; the rest of the world considers that if HD hasn't shown up by 12-13 months it is going to be very mild and not prevent dogs from having a normal life-span (the exception being the ones that REALLY work their joints hard for up to 14 hours a day).

As he is obviously NOT breeding stock, the only reason for xraying him is to confirm your suspicion that he has HD or ED, if that situation ever arises. Or, if you will be putting an expensive amount of time into training him for a specific task, xray at or after 12 months to see whether his joints look likely to give him 10+ years of working life. Otherwise, if you find out who his parents are and that they have KC registration, you might care to have him officially certificated to add to the knowledge about his parents' genes for dysplasia.
Pooches not needed for showing (conformation) and breeding SHOULD be neutered. But don't listen to the old wives' tales. There is only 1 guaranteed effect of neutering - that pooch can longer produce pups. There ARE, however, a host of POSSIBLE benefits and consequences, depending on the age at which the pooch was neutered. See http://pets.groups.yahoo.com/group/The_GSD_Source/links/Neutering_001198315291/ for the most up-to-date research on those side-effects, so that you can choose the age intelligently.
The proper place to ask questions about GSDs is in a couple of the 300+ YahooGroups dedicated to various aspects of our breed. Each group's Home Page will have a "mission statement" telling you which aspects they want to talk about, and below that will be a Monthly Activity "calendar" so you can tell whether the group is "dead" or manageably active or so over-active that you couldn't cope with all that traffic.
