Yes as the French Bulldog grows and gets older and grows into an adult the French Bulldogs ears will go up and stand straight up.
All French bulldogs ears do go up and stand straight up when they get older.
When the French Bulldog is just born and is a puppy they will usually have floppy ears but eventually by 5 or 8 months of age the French Bulldogs ears should point upwards.
Sometimes just one of the French Bulldogs ears stand straight up and then later the other ear stands up.
But most times a French Bulldogs ears will both stand straight up at the same time.
