Today we noticed Simba is developing a little bump on the top of his head. After doing a little Google research I learned that it is most likely the occipital bone (occipitus), or also known as the "bump of knowledge". Did/does your lab have this as a puppy? Is it normal among labs?
Totally normal. Can sometimes look more pronounced when, as one of my pups did, they bump their head while zooming round and it swells up. Took ages to go back down too.
Haha honestly he is always bumping his head, I hardly keep track anymore, so that could definitely be it. Thanks for the reassurrance.
