1. Dogs have an incredible sense of smell—up to 100,000 times better than ours! They have more than 220 million olfactory receptors in their noses, while humans only have around 5 million.

2. Dogs can recognize up to 250 words and gestures, and they can even understand the tone of voice we use when we’re speaking to them.

3. Dogs can see in the dark better than us. They have a layer of cells in their eyes called the tapetum lucidum which reflects light back into the retina and helps them to see better in low light.

4. Dogs can sense when something is wrong or when you’re feeling down. They’ll often come and sit with you or give you extra cuddles when you’re feeling blue.

5. Dogs have an incredible sense of direction and can find their way back home from miles away. They use a combination of smell, sight and sound to remember the route they took.

6. Dogs can often tell when you’re about to sneeze. They have a special ability to sense subtle changes in our body language, and they can detect the slight changes that happen right before you sneeze.

7. Dogs can also tell when you’re happy or sad. They have the ability to sense changes in our breathing, body temperature, and even the amount of sweat we produce.

8. Dogs can sense when you’re getting sick. They can detect changes in your scent that you don’t even notice, and they’ll often come and comfort you when you’re feeling unwell.

9. Dogs can sense when someone is going to epileptic seizures or diabetic shock. They can detect the changes in smell, behavior and body chemistry that occur before a seizure or shock happens.

10. Dogs can detect certain types of cancer. They’re able to sniff out volatile organic compounds (VOCs) in the breath, urine or sweat of a person with cancer, which is why some organizations are training dogs to use their noses to detect cancer in humans.

I have heard all of these before but had forgotten some,
I was adopted by a Black & Tan Bluetick cross hound a year ago last April, Murphy is smart, affectionate and laid back except the he hears the UPS truck pull in the driveway, he thinks the driver is coming to see him
The Vet said he is between 7 & 9 years old, but acts likes more like a puppy than an adult at times.
It has been a lesson in patience training him, he is hard headed, and as strong as an ox but he is learning!!
Maybe I'll get him trained before I die
