If it's a tick, you should be able to see its legs if you can part the dog's hair closer to where it's attached.

That is 100% a tick.

Sure looks like a tick

Tick. My dog had this on his lips once and without thinking I thought it was a rice grain and pulled it off. It infected his lip.

Sure don't look like a skin tag, so more likely a tick.

Never had to deal with a tick, but I was in the scouts and did a lot of outdoor activities and tick removal is one of those things they cover a lot. Use an oil or petroleum jelly to smother it and it should release and back out on its own. The other method widely taught when I was a kid was to light a match, blow it out and then use the still hot end to coax the fucker out; but I'm pretty sure that's discouraged these days.

lol, my dog had one of those. I also thought it was a skin tag, at first. I live in a place where there aren’t a lot of ticks; we had adopted her from another part of the country. One day, the sucker was suddenly like 3 times the size, so I took a closer look. I had been giving that little bastard pets the whole time.

Thanks for all the responses. It fell off before I noticed people had responded (Mlem doesn’t notify) so all is well that ends well.
