Having been in the vet industry for several decades....may I suggest you ask your vet what he/she recommends. Calcium is necessary for the heart to maintain its heartbeat, for the uterus to contract during labor, is used in the milk production and also is given to the pups for development. A bitch that is too low on the proper calcium requirement for its system can suffer pre-eclampsia which means she goes into problems prior to whelping her litter....may seem to stumble around, appear blind, tremble, salivate, vomit, etc and will most likely die if this matter is not treated by a vet as soon as it manifests. During labor, the uterus requires calcium to cause it to keep up its work to deliver the pups and can go into dystocia (become too drained to finish the job). My vets have always recommended supplementation regardless of diet within a week of whelping and continuing until pups are eating solid food. Again, check with your own vet...it is better to be safe than sorry later and there may be more than one school of thought on this out there. Debbie In a message dated 6/9/2008 2:07:30 P.M.

When you add liquid or pills, the bitch's body actually becomes less efficient and once she has her babies you are setting up for a case of eclampsia. **************Vote for your city's best dining and nightlife.
