There have been many instances in which French Bulldog owners have witnessed their pets choking while eating. This problem is caused by the excessive amount of tissue crammed into the nose and throat of Frenchies. For some of these dogs breathing is a struggle and imagine trying to force some food down the throat while fighting for air. Additionally French Bulldogs tend to be overweight which exacerbates their breathing problems.
Last but not least any short-nosed dog has problems swallowing which can result in food getting into its airways and lungs causing pneumonia.
Some gagging is to be expected with Frenchies but excessive gagging and choking on food indicate distress and require immediate medical attention.
