@Motala - That is good that you talked to Jan and glad to hear that she had not been spayed. I still think that your Vet and you should connect with Dr. Gonto about your girl's blood work and blood gas results and if he has any thoughts about it.
Welcome aboard, but do share his registered name ? Who are Dad and Mom and what was his date of birth so we can be sure to add him to the Basenji pedigree on-line database (with a photo ???) for the world to share him.

@basenjilovers - She is very cute, please make sure that DNA testing was done for Fanconi and PRA. And if not or you are not sure, you can get the test kits at www.ofa.org. You do the test as it is a cheek swab.
