Corgis are known for big, upright ears above their heads. As their ears develop, most will be floppy and gradually stand up around 6-10 weeks. The exact timing of this depends greatly on genetics, ear shape, texture, weight, and ear size. Around 12 weeks (3 months) if a corgi puppy's ears are not upright, I will generally recommend taping. This airs on the side of caution, as there are others that will wait until 16 weeks (4 months) before taping. However, I believe that if ears are not standing up by 20 weeks (5 months), the likelihood that they will stay floppy is high. Of course, corgis are lovable regardless if their ears are up or down. It is entirely up to you whether you decide to intervene or sit back. If you do decide to tape, below are basic instructions on how to tape a corgi's ear(s).
This is Lavender; both her ears stood around 9 weeks. In this picture, she is 12 weeks old. Her left ear fell yesterday, just in time for my ear taping tutorial. Somehow the universe knew I needed a model!
Step 1: Gather the Supplies
You will need a pair of scissors, a paper roll from left over from the toilet papers or paper towels, and masking or painter's tape. Don't forget you will also need high value treats and your victim puppy.
Step 2: Cut the Paper Roll
Trim the cardboard roll into the general shape and size of your corgi's ear. Keep in mind that it should be slightly smaller than the ear itself. The cardboard acts as boning or rigid lining, providing structure to hold up the ear. A good way to think of it, is as support beams in a building.
Step 3: Measure Ear Lining
Make sure the the cardboard is the right fit, trim pieces as needed. The cardboard sits on the inside of the ear, as close to the base of the ear as possible.
Step 4: Cut Tape and Wrap
Take about six inches of tape and place on the cardboard, as shown. As you can see, the tape is placed against the bottom of the cardboard; you want to wrap around the base of the ear. I find it best wrapping clockwise (left to right) but find out what's best for you. You might have to try a couple of times before getting the wrap correctly. It's easier with someone is holding the puppy or yummy treats.
Step 5: Check Wrap
Check to make sure the wrap is snug but not overly tight. Be sure that the ear canal is still open and allows for air circulation. Cutting off circulation can leave moisture trapped in the ear and lead to an ear infection.
Step 6: Wrapping Up (haha!)
The right wrapping will make the ear stand upright. If your puppy's ear(s) are still flopping over, they are not being supported; try to tape closer to the base or alter the shape of the cardboard. It will take some trial and error to get the right fit for your corgi. The correct structure will result in the tip of the ears and the nose making an imaginary upside down triangle. As well, adding a spoonful of cottage cheese to your puppy's diet with each meal will provide extra calcium to build support from within.
