Extremely tiny. No more than 2mm in length.
I’ve pulled a few off. And there are no dogs in my neck of the woods. Only coyotes.
Pulled off me or my clothes after Powderhorn trip. Then into frig before image. The one in center looks different than usual dog tick.
Could have been picked up in Nashville or West Lafayette. The last few photos (mostly black) are through a microscope. If anyone can confirm the ID, please do so! Thank you!
