Is it true that spaying before the first heat can adversely affect growth and bone development?

Hi Cindy,

I feel as though I should have you on speed-dial. . . Recently you answered a question we had about x-raying for dysplasia and now we are seeking advice again. Whether or not we find Abby is dysplastic, we plan to have her spayed as we do not want to breed her and feel this should be left to people who know what they're doing anyway. However, in speaking with friends who raise and show goldens we were told it is best not to spay until after the first heat. Our vet said there are health arguments for spaying before that heat as well as arguments to allow the dog to go through the first heat. Having read all the literature she provided, pro and con, I am now looking for recommendations from more experts, namely you and Ed, because of your experience with GSDs. Is it true that spaying before the first heat can adversely affect growth and bone development? What about temperament?

We had spayed previous shepherds (2) and a labrador years ago and didn't notice any problems but since animal health knowledge progresses every year we want to be sure we do the right thing for this great puppy when the time comes.

We live in a semi-rural area with many, many dogs. Although our yard is fenced, from past experience I know that is no deterrent for a determined male. Even though she is never outside without us I really don't want 21 days of fighting off potential suitors during a heat and confining her within the house to washable surfaces as well.

We would appreciate any advice you can give us. You all have such a wonderfully informative site but I didn't find any information on this except in the discussion areas. I will feel more comfortable following your recommendations / information than those given by folks I don't know!

Again, we thank you so much for the service you provide via the net and through these emails.

Cindy
