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.
You want to start breeding does (female rabbits) when they are reaching maturity. For small-medium breeds, they can be bred at 5-6 months old. Larger breeds can be bred at 8-9 months. Bucks (male rabbits) are usually ready around 6 months old if a small breed, 7 months if medium, and 9 months for a large breed.
