Is it a disease for a dog to run diagonally?

It is not a disease for a dog to run diagonally. This is a sign of the dog's self-balance adjustment when running to avoid knocking over objects in front of it while running. This protective function can also ensure that the dog will not be hit on the head when it hits an object. Generally, it is more common for puppies to run diagonally. As the dog grows older and has more experience, this situation will no longer occur.
In fact, the owner carefully observes that the dog is running diagonally but the body is in a straight line. As mentioned above, this is the dog’s normal protective function and the owner does not need to worry too much. As long as the dog does not have other adverse symptoms, it is normal.

Moderate exercise contributes to the physical and mental health of dogs

Dogs of different sizes also have different amounts of exercise. The daily exercise time for small dogs should be about 15 minutes, the daily exercise time for medium-sized dogs should be about 30 minutes, and the daily exercise time for large dogs should be about 1 hour.
The purpose of exercise is not to consume calories, but to maintain the health of blood circulation, muscles, ligaments, joints and internal organs throughout the body.
