The recommended daily exercise for dogs varies by size, age, and energy level. Small breeds may suffice with short walks and indoor play, while larger, high-energy breeds often require over an hour of more intense activity. Puppies and young dogs, full of energy, might need several shorter sessions of play and exercise throughout the day. Senior dogs benefit from gentler, shorter activities tailored to their mobility. Always consider the dog's health and consult a veterinarian to customize an exercise routine that promotes optimal health without risking injury or overexertion.
