Why are most dogs so hellbent on, and obsessed with, playing fetch, never getting tired of the game?
That's interesting. Can playing fetch too much be harmful for dogs?
It is recommended to monitor a dog's playtime to avoid overexertion. Also, using appropriate fetch toys can prevent injuries. It is always best to consult with a veterinarian about the appropriate amount of exercise for a specific breed.
