Licking objects every once in a while might be a simple way for pooches to learn about their environment. On this occasion, it would appear that a puppy has decided to take a minute to learn about the taste of human food.
Although some might think this little helper is simply licking the dish to get it a bit cleaner, it might be a tad more reasonable to assume the doggo is just experiencing the smell of the food remaining on the forks and spoons in question.
