You're speaking with Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply. Please be patient. This may take a few minutes.

I'm sorry that your question wasn't answered in a timely manner. Resorption (or mummification) is more common a cause of fetal loss than abortion. Bitches with hypoluteoidism (a lack of progesterone production by the corpus lutea (the structures which the egg follicles become)) may experience recurrent resorption, mummification, or abortion. There are quite a few possible causes of resorption, however, and an inadequate uterine environment is more likely than a primary infection. In general, resorption should prompt a search for an underlying cause of such an environment. This can involve serology or PCR testing for Brucella canis and canine herpesvirus-1; virus or bacterial isolation from microbial cultures from feti, placenta, milk, or vaginal secretions; necropsy of feti; serum progesterone level assessment (>2-3 ng/mL is necessary to maintain pregnancy); thyroid hormone assessment; and routine laboratoryy testing - complete blood count and serum biochemical profile. Please respond with further questions or concerns if you wish.
