my little schnauzer bitch who should hopefully be 3 1/2 weeks pregnant, suddenly started being sick yesterday morning , and refusing food i assumed it was morning sickness but this continued all day and into the early night then she started having very bad dioareah with blood through it,i called the vet on calls last night who told me to give her 20ml of bolied water salt and sugar but she brought this all back up called vet again who said to bring her into the surgery,he took her temp which was normal but has kept her in and put her on a drip, how will this affect her if she is pregnant? how long does it normally last, its been 2 days since she ate, phoneed vet offered to bring in cooked chicken and rice but he says no food? house just feels so empty ant the moment.
