Glands in the cervix and the walls of the vagina normally produce a clear mucus.

Similarly, the time that it will take for your dog to digest his food also depends upon what type of food he eats. Generally speaking, raw food and canned food will move through his system faster than dry food; it typically takes between 4 and 6 hours for a dog to process a meal's worth of canned food. On the other hand, it may take as many as 8 to 10 hours for the same dog to process dry food completely. Other Factors
