Many times people forget to smile, but the man's friend is always there to remind him and show him "how to do it"! Not only through the guides, but through the power of example! Dogs laugh just like humans, only a little differently. Veterinarians have made an amazing discovery: dogs smile and laugh out loud by… panting!

Recently, a team of researchers in veterinary medicine conducted a study that showed, with the help of a pulse monitoring device, that quadrupeds express their joy through the banal panting. The dogs used in this study were given to listen to recordings of other dogs' panting. The result was truly impressive! They began to play, to wag their tails, and the expression on their faces showed joy. Experts say that this exercise could be useful for dogs in shelters: these tormented animals will be able to alleviate the stress produced by that scary space.
