Not necessarily. A five year old dog with an excellent pedigree, but now related to everything in the breeders kennel will do them not so much good as keeping a young bitch in his place.
That dog can produce puppies for another five years easy.
Let's say that this dog is out of a World Sieger and World Siegerin, how many of us would take him for $1500, on the pedigree alone? However, there is something that does not ring true on the x-rays. If the x-rays looked normal and good they would probably have sent the pre-lims in and retested at two. Testing him at five years, even a dog with ok hips and elbows may not pass now. So if the dog had an Awesome pedigree, and this x-ray statement, my guess would be that they are not being completely up front.
Depending on the training, accomplishments, h&e, temperament, looks, medical history, and registration, I do not see this as out of the ball park for a 5 year old dog. With any of the following, awesome pedigree, a conformation champion, high acheivements such as SAR dog, OTCH, MACH, SchHIII, etc., proven producer of excellent dogs, the price should go up considerably.
