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.
This can range from 45 days to 120 days. Ideally, you should have your breeding season between 45 to 60 days, but of course this varies between farm to farm and ranch to ranch. 1  Check the breeding herd[s] regularly to check up on the bull's progress with breeding the cows/heifers.
