I have a litter of bullmastiffs that have the diarrohea. I have been giving them prokolin and Lectade to help with dehydration, but it is getting worse rather than better. It's spraying out the one like a jet. They are on scrambled eggs made with water once a day, with chicken and Royal Canin weaning food twice a day. There were on raw minced beef - the extra lean but have taken them off it in case this was what the problem was.
