Some dog ear scars do flatten on their own, but it depends on how much excess tissue is involved and how your skin heals. Minor puckers caused mostly by post-surgical swelling often resolve within 3 to 6 months as inflammation settles. Larger, more pronounced dog ears with genuine excess skin are unlikely to flatten completely without a revision procedure.
What Causes the Pucker in the First Place
A dog ear forms when there’s unequal tissue on either side of a surgical closure, or when the wound’s shape forces excess skin to bunch up at the ends. As a surgeon pulls the central part of an incision together, the corners experience rotational and compression forces that push tissue outward and upward. When that bunched tissue exceeds the skin’s natural ability to absorb it, you get a visible bump or fold at one or both ends of the scar.
Dog ears are more likely when a wound’s length-to-width ratio is less than about 3 or 4 to 1, when the two sides of the incision are different lengths, or when the angles at the ends of the closure are too wide. They’re common after tummy tucks, breast reductions, top surgery, and any procedure that closes a circular or irregularly shaped wound in a straight line. Skin elasticity, body location, and individual healing tendencies all play a role in how prominent the dog ear becomes.
The 3-to-6-Month Window
In the early months after surgery, swelling can make a closure look lumpy even when no true excess tissue exists. These are sometimes called “false dog ears,” and they tend to disappear on their own as the swelling resolves, typically within 3 to 6 months. During this phase, the scar is still actively remodeling: your body is breaking down and reorganizing collagen fibers, and the tissue gradually softens and flattens.
This is why most plastic surgeons ask patients to wait at least 6 months, and often 6 to 9 months, before evaluating whether a dog ear truly needs correction. What looks like a permanent problem at 8 weeks may be noticeably improved by month 5 or 6. If you’re still in that early window, patience is genuinely the best first step.
Signs It Won’t Flatten on Its Own
After 6 to 9 months, whatever you’re seeing is close to your final result. A few indicators suggest the dog ear is structural rather than swelling-related:
- You can pinch a distinct fold of excess skin at the end of the scar, even when the surrounding area feels soft and healed.
- The bump hasn’t changed noticeably between months 3 and 6, suggesting the tissue itself is redundant rather than inflamed.
- The dog ear is large or sits at a right angle to the skin surface (a “standing cone”), which is the most common and most visible type.
Skin elasticity matters here too. Thicker, less elastic skin (common on the trunk and in older patients) is less capable of absorbing that extra tissue over time. Thinner, more pliable skin in areas with good blood flow has a better chance of gradually smoothing out.
What You Can Do Without Surgery
Non-surgical options won’t eliminate a true dog ear, but they can improve the overall scar quality and may help a borderline case settle more smoothly. Silicone sheets or gel, applied as a first-line scar treatment, can reduce scar thickness and help the tissue soften. Gentle scar massage, once your surgeon confirms the wound is fully healed, works to break up adhesions beneath the skin and may encourage the tissue to lie flatter.
Pressure therapy is another option. Compression garments or kinesiology tape applied over the scar can discourage tissue elevation. Kinesiotape is placed with no stretch directly over the scar and left in place for 2 to 3 weeks per cycle. It’s thought to weaken subcutaneous adhesions and improve scar softness, and many patients find it more tolerable than traditional pressure therapy, which requires sustained compression of at least 24 mmHg for 30 or more minutes daily.
These approaches work best when started soon after the wound has fully closed and continued consistently over several months. They’re most effective for mild puckering rather than large redundancies.
What Revision Surgery Looks Like
If the dog ear persists beyond the 6-to-9-month mark and bothers you, a revision is a straightforward procedure. The surgeon removes the excess tissue, usually as a small wedge or triangle of skin, and re-closes the area. Several techniques exist, but they all involve trimming the redundant skin. The tradeoff is that the scar typically becomes slightly longer in the process.
For many patients, especially after tummy tucks, this can be done in the office under local anesthesia with a relatively quick recovery. It’s not a major operation. The revision scar itself then goes through its own healing timeline of several months, but because the underlying problem (excess tissue) has been physically removed, the result is a flatter contour.
A Realistic Expectation
If your dog ear is mild and you’re fewer than 6 months out from surgery, there’s a reasonable chance it will improve significantly or resolve entirely as swelling fades and scar remodeling progresses. Silicone therapy, massage, and compression can support that process. If it’s moderate to large and still prominent past the 6-to-9-month mark, it’s unlikely to flatten on its own, and revision is a reliable, low-risk fix. The key variable is whether what you’re seeing is mostly swelling or mostly surplus skin, and time is the only way to tell the difference.
