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.
1 Since a dog can be bred at any time, unlike bitches, waiting for two years is not a problem, whereas a bitch often has a season just before two years of age and then has to wait until 2.5 or three which sometimes presents problems in trying to time her litters.itches. 1  A bitch should be atleast 18 months of age at the time of breeding or the season closest to the second birthday is a good one to start breeding. 2  However in some breeds, one may need to wait one more season before beginning.
