Just petting a dog has been shown to lower a person's blood pressure.
Your dog’s sense of smell is 10,000 times better than yours. Dogs can track people and other animals across many miles, detect dangerous substances and have even been known to sniff out signs of cancer.
Adopt your next pet from a shelter or rescue, or only buy from a responsible breeder who can show you where the puppy was born and where the mom lives. And you can do even more by only purchasing pet supplies from stores that don't sell puppies.
