Now that I have your attention... you did read that correctly! Giving your dog 15 minutes of sniffing burns the same amount of calories as a 1 hour walk.

It's unlikely that your dog would contract a virus from sniffing the same spot on your pants where a stray dog had sniffed, especially if the stray dog did not exhibit any signs of illness. However, it's always a good idea to practice basic hygiene and cleanliness to minimize any potential risks to your dog's health.
