Whether you plan to raise a champion show bulldog, or a well-groomed companion, ear gluing might be something in which you're interested. The "rose ear" shape is preferred for show bulldogs, named for the shape created by the interior of the ear when viewed from the front.The ear itself folds inward along its back edge and rests against the skull. Aesthetics aside, the "rose ear" shape also allows fresh air to get into the ears, thereby reducing the risk of moisture-related infections. Some bulldog puppies' ears "rose" all on their own, while others ears need a little help.
Secure the leash to the puppy's collar.
Sit down on the floor with the puppy between your legs and most of the leash under your backside.
Gently lift one of the puppy's ears outward. Then, pull it down toward its shoulder. Notice the crease that forms along the back of the ear.
Apply a line of glue to the back of the ear along the crease. Apply enough glue so that the ear will adhere to the fold and to the side of the puppy's head when held in place, but not so much that excess glue will ooze out from the point of contact.
Fold the ear back into the proper "rose ear" position and hold it in place for 3 to 5 minutes, or as long as indicated on the glue container.
Smooth out and remove any excess glue with a cotton swab.
Repeat the process with the other ear.
Proper "rose ears" are identified by their position on the head as much as by their shape. They should be set high and as far from the eyes as possible. The upper edges -- especially the front, inner edges of the ears should be level with the top of the skull. The glue will eventually wear off. If the ears retain their new rose shape, then the ears will not have to be reglued. However, if they do fall out of shape, they may be glued a second and third time. If the first gluing attempt fails immediately, wait one week and then try again. If it fails a second time, see a professional before making a third attempt. Ideally, a bulldog puppy should be 7 to 10 weeks old when having its ears glued for the first time (See References 3).
Do not allow glue to come into contact with a puppy's eyes, nose, or inner ear. Never tug on a puppy's ears or restrain it in a way that causes it pain. If you have never before attempted to glue a bulldog's ears, having an experienced person help you is highly recommended. Large, thick ears will prove harder to train than small, thin ears.
