People stink more than they know.
Oh my gosh.
Just HOW do dogs do it?
People stink more than they know.
You are probably correct!
When my daughter was in college, we played the “Where’s Waldo Coming home game” with our dog...When she would drive home for holiday breaks, etc.,
I would let pooch out in back yard after daughter had parked car in front...While dog was outside in back, daughter would come in the house and hide somewhere in the house.
After she hid, I would let dog in as usual—within seconds he would catch her scent.,..he would raise nose up in the air and he would literally trot/run thru the house until he found her...by her scent ;)
It was fun to watch...
