Dogs have a bony prominence at the back of their head called the occipital protuberance**. This is a normal feature and not a bump in the sense of a growth or abnormality.
Here's a breakdown:
* Occipital protuberance: This is a bony bump that's part of the skull. It's the point where the skull joins the spine. It's more prominent in some breeds than others, but all dogs have it.
* Other bumps: Dogs can develop bumps or lumps on their head due to various reasons like:
* Skin growths: These can be benign or cancerous.
* Infections: Some infections can cause swelling and bumps.
* Parasites: Certain parasites can cause bumps under the skin.
If you notice a bump on your dog's head that is unusual or growing, it's important to consult your veterinarian to rule out any underlying medical conditions.
