I own 2 dogs
I can't believe that the dog was the first animal to be domesticated?
I believe that they were much large than today's domesticated canines
It is crazy to think that they found a dog buried next to a human 14,700.
One of the best guard dogs are the Belgian Malinois. Are you a bot?
I like Belgian Malinois dogs. However, there ancestor species are extinct. 
Dogs, like many other animals, cannot sweat. It is important to keep them cool and to not let them over-heat.
Yeah they can use thermoregulation to make sure they stay the right temperature, even if the surrounding temperature is higher or lower.
