Oxytocin is a mammalian hormone that plays a major part in female reproduction. Often called the "Love hormone", it makes us feel all soft and fuzzy inside and the next thing you know, we've fallen in love!
In dogs, the hormone is released in the mother during birth and nursing. This hormone tells the mother that she is doing what she is suppose to be doing, nursing her puppies.
Oxytocin helps the Momma dog to feel relaxed and calm.
Oxytocin aids puppies in bonding with the mother and humans as well.
It plays a part in what makes us adults crumble into a pile over a litter of cute cuddly puppies. The "Awwwww" factor.
I guess I should have posted this for ♥Valentines Day, but heck, Love is great anytime, right?!
