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.
If you are interested in breeding your dog, here are some suggested methods that breeders use. 1  Breed every 48 hours from first acceptance until she refuses to âstandâ. 2  Breed two or three times with a gap of 48 hours between breedings.  Breed on specific days, eg. Days 11 (from first sign of heat) and 13 or 12 and 14.
