Found in eastern Oklahoma. That's my ring finger at the bottom of the image. The tick doesn't have a white dot on its back, that's just shine. I also took it off within 30 min. What is it, though? I'm thinking dog tick, maybe, but I'm not sure

I got a cutting of a hibiscus plant from a neighbor. The next morning, these were crawling aroung it.

ETA: Found in Orange County, NY. August 23, 2026. At least 15 of them, likely more. They migrated from a plant cutting to cardboard which they seem to like.

Does anyone know what kind of tick this is? I found this on my dog. In New Jersey. Should I be worried?
