OK, there have been a lot of arguments about whether PennHIP or OFA is better.  I think I finally have THE compelling reason why PennHIP is better.

You can do PennHIP at six months of age rather than two years for OFA.

Think about it.  You have a dog and it's full of potential.  You train her, you campaign her in AKC or NAVHDA or any other events to prove her.  You wait for two years and get shabby hip results and what do you do?  I know some folks just ignore and breed her anyway.  Respected breeders right here in Maine, for instance.

In the alternative, you raise your pup to six months and get shabby scores.  You can spay her.  If it was important that she be a breeding prospect you can sell her and get a new pup to try.  In fact you know exactly how shabby the scores are, and guess what?  You can do something about it like keeping her fit and lean. 

The potential savings of your time, money and effort, plus love and affection for the dog is worth every penny of a PennHIP evaluation.  You can make a rational decision instead of succumbing to kennel blindness.  This one fact trumps all others.

But lets take some of the other arguments, shall we?

OFA is more accessible because any vet can do it.
Let me ask you, if you transmission blows in your truck, do you take it to the Kwik-E-Lube?  Or would you prefer someone who is actually trained in repairing transmissions?  The fact is anyone can find a PennHIP trained and certified veterinarian to take the radiographs.   Here in Maine, you can find a vet from Fort Kent to York County and everywhere in between.  You might have to drive a little farther than your usual vet, but you know the job will be done correctly.

OFA is less expensive.
A PennHIP evaluation needs only be done once.  For best results you need to repeat OFA every year.  Also as I said before, what is the cost of making ready a dog, only to find her with less than perfect hips?

It's too difficult for a veterinarian to become certified.
PennHIP seminars are run at all the major veterinary conferences.  They get certified at places like Las Vegas and Orlando, and the trip is tax deductible and counts for Continuing.

OFA is just as good.
It's not.  It's been statistically demonstrated, PennHIP is better.
