There is no specific duration for a dog’s flashback, it depends on the dog’s condition.

I believe parents must have heard of the term "return of the light". It usually happens to people, but it also happens to dogs. A "return of the light" means that the sick body suddenly no longer feels sick, and the dog's spirit suddenly improves, but it continues. It won't be long before he leaves this world. Many parents hope that their dogs can spend more time with them, but the time for returning to the light is not necessarily certain. Some are long and some are short. We can only wait for the dog to be energetic during this period. Meet all its needs, tell it what parents want to say, and let the dog go to another world without regrets.

A dog's life is relatively short for humans. In this limited life, parents should let their dogs live as many years as possible and spend more time with them. They should not feed their dogs too many miscellaneous foods and always pay attention to their dogs' health. Conditions, vaccinations and physical examinations are required every year to prevent unknown conditions.
