I'm so sorry to hear about your friends saluki. I'm sure they are heartbroken and I pray they are able to get pregnant again with a positive outcome.
Please remember though, everyone is different. If you are worried about your levels, you can have them checked every now and again to make sure you are where you need to be come the time for you to have children.
I'm sorry too for your loss....sounds like their child and you would be close.
