What is this bump on my dogs head?

A little worried at what this might be? Any input appreciated. She doesent seem to be in pain when I lightly touch it. And she still runs around with a lot of energy. Should I take her to the vet? She’s 11 years old

The struggle is real

Am I reading too deep into this?

I don't get it.

My cousin sent me this. I don't get it.

Found on r/TIHI, I don’t get it

I have never understood this one

I don’t know the method, and neither does my friends

I don't get it. Is it a breakup thing?

I know what lemmings are, but what does this have to do with Disney?
