This is a heartening story that is good for 3 hoorays for that mother dog. Truly there is a natural bond between man and dog that's why the moniker man's best friend. It is a given that when man goes hunting, the dog is his side kick. When a man is lonely, the dog is the first one to cheer him up. Pardon me if you are a cat lover but cats cannot come near the level of dog's closeness to man.
I had seen on tv an excerpt of a youtube video where a female dog and a female cat were lying down side by side. Between them are the kittens and the puppies that are nursing in a confused manner - some puppies are getting the milk of the mother cat while some kittens are busy with the nipples of the mother dog. It's not only funny but amusing and interesting to see the peaceful co-existence of a dog and a cat.
