DISCUSSION 
A. J. Wilson, Ohio State University, Colum- 
bus : Did I understand you correctly, one animal 
technician takes care of about 400 animals? 
Dr. Templeton : No. There are 122 runs and 
1.5 full-time employees are needed for cleaning 
them only. It takes two full-time caretakers to 
feed, clean, and do some research. It is difficult 
to really designate what is not research cur- 
rently because we are doing research with the 
same personnel. As for the cost of these dogs, 
there's a fellow here who breeds beagles com- 
mercially. I think he could address himself more 
clearly to the costs of raising a dog, especially a 
beagle, to six months of age if anyone really 
wants to pursue that. But I feel that $150 for a 
dog like this comes pretty close, if you have the 
right kind of capital investments and include all 
the top personnel and other expenses into raising 
one of these dogs to six months of age. 
M. L. PovAR, Brown University, Providence, 
R. I. : Can you tell us a little about your experi- 
ence with hip dysplasia? 
Dr. Templeton : Hip dysplasia is endemic in 
all large breeds and we do have a hip dysplasia 
study. We can just say we have a lot of 
it. We have calculated hereditability on this, 
and it has a hereditability estimate of around 
0.35, 0.4, or something on that order. I think 
that we have reduced the instance by selection, 
much as they've done in the Swedish colony of 
German Shepherds or the Swedish Army dog 
colonies. It is a, problem in all large breeds, and 
there are some breeds in which all members are 
dysplastic as you know. Every dog is radio- 
graphed at six months of age and it is repeated 
every six months as long as the dog is available 
to the colony. That is one of the criteria for 
selecting breeders. 
H. P. Schneider, Hahnemann Medical Col- 
lege, Philadelphia : Would you include the grey- 
hounds when you say that hip dysplasia is a 
problem in all large breeds ? 
Dr. Templeton: This is a very confusing 
subject. I have seen one radiograph alleged to be
