Causes of red eyes in French Dou:

1. Unreasonable diet. Breeders don't pay much attention to supplementing their dogs with vitamins and water, and always feed them food with high meat and fat content. At this time, French bulldogs may have red eyes.

2. If the breeder does not pay attention to the dog's eye care or does not do enough cleaning work, it will cause the dog's eyes to be infected with germs, resulting in red eyes and increased eye feces.

3. Canine distemper can also cause French Bulldogs to have more eye droppings, red eyes, yellow and purulent eye droppings, purulent secretions from the nose, rising body temperature, vomiting and diarrhea, and not eating. Not drinking and other situations arise.

4. The eyes of French Dou are repeatedly stimulated by the eyelashes for a long time, which will lead to tears and eye feces and the eyes to become red.

5. The redness of French Dou’s eyes may be physiological. The French Dou’s forehead is short and the blood vessels are congested, which will cause red eyes.
