If a French Dou is treated for heatstroke in time, it will usually recover in about 1 to 7 days. Dogs with different degrees of heatstroke have different recovery times. If your dog has mild heatstroke, move it to a cool place in time and replenish it with water. The dog will usually recover in about half a day.
However, the French Bulldog's heat stroke is more serious, with symptoms such as convulsions, convulsions or accelerated heart rate. The owner needs to send him back as soon as possible after cooling him down. Go to a pet hospital for treatment. In this case, it may take a few days for the dog to recover.
