Dogs are man's best friend. But this does not mean that they are not compatible with other animals. In fact, it is the exact opposite! We have seen dogs befriend monkeys, horses, and even elephants!
Contrary to popular belief, cats are not their sworn enemies in the video below, you will see a dog who is not just a cat friend, but who takes the relationship one step further to nurture him and be part of the cat family!

The lovely golden retriever sees mom breastfeed and care for her kittens, and decides she can do the same. The dog allows cats to feast on her and accepts them as her own! You have learned that being a surrogate can be very rewarding, and eventually you can see your mom cat massaging a Golden Retriever as a thank you for her help. Very beautiful!
