A number of non-infectious causes can result in diarrhea. These include lactose intolerance, irritable bowel syndrome, non-celiac gluten sensitivity, celiac disease, inflammatory bowel disease, hyperthyroidism, and a number of medications. In most cases, stool cultures to confirm the exact cause are not required.
Most dogs are first bred between the 10th and 14th day after the onset of proestrus. As long as the bitch will accept the male, mating every other day for a total of two or three matings is generally considered sufficient. However, signs of proestrus are not obvious in some bitches.
Female dogs will carry young anywhere from 56 days to 63 days from breeding.If a big litter she can have the pups at 56 days.Sometimes a female dog will seem to go beyond 63 days,but not late,as may have not conceived on first breeding,but if goes beyond a week over 63 days,consult your vet.
