"First: meet Valerie, a Jack Russell-Chihuahua mix born with a perfect heart shape on her side (at the time of this pic, she was 16 days old): Aww! But there are more reasons to love dogs than their obvious cuteness factor&amp;amp;#8212;in fact, having a dog can come with some health benefits that you might not have known about. 1: They make you happy and also reduce stress and anxiety. Studies have shown that dogs are attuned to their owners&amp;#x27; emotions&amp;amp;#8212;so much so, they may even mimic your behavior (like yawning!). But they&amp;#x27;re also great for elevating your mood and reducing the blues&amp;amp;#8212;some doctors say they may be better better than anti-depressants. 2: They can possibly sniff out cancer. Dogs&amp;#x27; noses are way, way more sensitive than ours&amp;amp;#8212;to the point that some of them may even be able to smell cancer cells! Some studies&amp;amp;#8212;involving people with lung or breast cancer&amp;amp;#8212;found that pups can distinguish biochemical markers of cancer just by sniffing someone&amp;#x27;s breath. 3: They may help detect low blood sugar in their diabetic owners. Again owing to their keen sense of smell, dogs can detect when there are fluctuations in blood sugar, alerting their owners that it&amp;#x27;s time to inject insulin. 4: They can improve your heart health. Dog owners tend to exercise more than people without dogs&amp;amp;#8212;after all, our four-footed friends need their daily walks! People with dogs have also been found to have lower blood pressure; plus, dog owners with heart problems seem to live longer than people who have the same heart problems&amp;amp;#8212;but no dogs. I love my cats&amp;amp;#8212;but I do miss having a pup! Do you have a dog?"^^<http://www.w3.org/2001/XMLSchema#string>
