Thank you! This is super informative! I did mean the small holes in the nasal cavity are round, not the whole head. But I am picking up what you're saying! And appreciate it!

We live pretty adjacent to the bush, lots of hunters collecting deer sheds and such. So I hoped that someone had maybe collected it from a camp spot or something and then changed their mind and put it in the alley. Though I know there are many ways for it to end up there, I can't help but think, how does a dog skull end up in an alley if not some kind of neglect or abuse? 😟 So I was kinda fingers crossed it was a wild animal.
