good luck w/ buck. keep us posted on his results.

Has he always been current on his vaccines? I know vaccines are not 100% fool proof but that does help.

And I would keep your other dogs away from any area buck has been in contact with. If possible maybe have a friend or relative keep at least the pup (due to his age he is still very suseptible to catch anything that is contagious). good luck parvo sure is a scary disease.
