Reabsorbed litters are usually due to low progesterone level during pregnancy. The pregnancy cannot be maintained unless the progesterone level stays up. Many breeders, of various breeds, are having to test the progesterone level during pregnancy and supplementing as needed. Another thing to check is the thyroid level. Bitches who fail to swell during their season can be low in thyroid. Also, failure to conceive and carry a liiter can be due to low thyroid. Now, I am not talking about low thyroid as in below the normal range. My repro vet likes to see 2.0 or higher in the breeding bitch. Barb Hively - PA DNA.

Out here on the west coast, I have not heard that much about problems with dogs that won't breed. To date, my stud dog has produced puppies from AIs, TCIs, surgical implants using shipped fresh semen and natural breedings....all done for various reasons. I do required progesterone testing on the bitches that come to him along with the other tests. And not the in house progesterone testing. Recently, a bitch came to be bred and the progesterone tests showed that she was not ready to breed until the 19th day! Before she had been successfully bred on the 11th day. My vet said everything looked good so we will see if she conceives based on her progesterone level. Yes, some of the bitches have missed but the vast majority have had puppies. On the other hand, when breeding one of my bitches, I have not had good luck with using frozen semen that has been shipped to me and know several people who also have not had good luck using frozen. One issue I do have is breeding a stud artificially because he can not physically do the job. For example, breeding a dog that has such bad DM or structural issues that he physically can not do it. That makes me crazy!!!! I have experienced & heard a lot about bitches reabsorbing litters. The repro vet that I use told me that from the seminars she attends across the US, the repro vets are seeing an unusual amount of bitches reabsorbing litters. This is not breed specific so they are thinking environmental issues. Kay Springer www.showboatgsd.com Home of Multi BISS & Multi Group Winning Ch.
