Different dog breeds require tailored exercise plans based on their physical and mental characteristics. For example, high-energy breeds like Greyhounds may enjoy running, while smaller breeds such as Pomeranians can benefit from indoor play like fetch. Swimming offers excellent cardio but isn't suitable for breeds fearful of water or with physical limitations. Breed-specific research and veterinary advice are essential in determining the most appropriate activities, ensuring they align with the dog's age, size, and health. It's crucial to avoid exercises that could harm specific breeds, such as jumping for large dogs prone to joint issues.
