How do dogs smell fear?
People who are feared have a distinct scent and it is amazing how effectively dogs can catch this. Usually when someone is scared they tend to sweat more, and dogs can easily smell this.
Apart from fear dogs can also smell various other moods – sorrow, anxiety and sadness. When you are anxious there is an adrenaline rush in your system which leads to increased blood flow and increased heart rate. The activity in your brain is reflected on your skin by means of scent, and your beloved pooch sniffs your anxiety.
Sniffing comes naturally to dogs. Digging out stories while walking in the neighbourhood is their favourite pastime, and sniffing helps a lot. So now when you take your pet for a walk, let them sniff around and explore stories. Also peeing at every nook and cranny is their way of leaving comments on the gathered stories. This is their social media, so let them enjoy.
