Dogs that are afflicted with ear mites will typically scratch at the ears excessively and shake their heads, even pulling out their own hair as they scratch. Some dogs will shake their heads so much that an hematoma of the ear will form (with blood pooling in the ear due to breakage of a blood vessel). Also a concern is when dogs will scratch at their ears to the point that damage is done to the ear canals or ear drums.
The hypertrophic scar is defined as a widened or unsightly scar that does not extend beyond the original boundaries of the wound. Unlike keloids, the hypertrophic scar reaches a certain size and subsequently stabilizes or regresses.
Some scars may be depressed while others may be raised. Hypertrophic scar is one of the kinds that are raised. This scar is often confused with a keloid, which is also a raised scar. In this article, I will provide a definition for a hypertrophic scar so that you can be able to differentiate between it and a keloid.
