If your Frenchie is having difficulty breathing, there are a few things you can do to help them. First, it is important to ensure their environment is clear of any potential allergens or irritants such as dust, smoke, and pollen. Additionally, keeping your Frenchie at a healthy weight can help reduce the strain on its respiratory system. Other strategies you may want to consider are providing your Frenchie with a humidifier to moisten the air they breathe and using an air filter to remove airborne particles. You should also consult your veterinarian about possible medications or treatments that may be suitable for your pet's condition.
