Bumps on Doxie's Head


#1
Hi,
We recently welcomed a new miniature dachshund to our family and just noticed bumps on his head. We tried looking online to identify what these were but that did not turn up any results. We've attached images here and was hoping members here could give us clues on what it is.

We hope you can shed some light on this, thanks!
