My dog has a growing, bruised head lump. What is it? How to remove?

Updated On September 23rd, 2025

Hi! Lucky developed a bump in his head about a year ago. At the time it was small, flesh colored, and his doctor said that it wasn't cancerous as his chemistry results indicated good health. Since then the bump has grown significantly and is colored like a bruise. Still, his labs are normal and the doctor can't diagnose the knot. Do you have an idea of what it could be and how I can remove it? He's in no obvious pain and is still a happy dog. I understand this might require a "cosmetic" surgery.

He only way to find out what it is, is to have it surgical removed. If it is growing and changing then it is not a cosmetic procedure, that warrants a medical reason to remove it. It may just be an adenoma or a benign cyst, but being on top of his head, is ir gets too large it will be harder to remove. I would try to schedule it as soon as you can
