I have had greyhounds for 12 years and none of them have ever had a tick . . . until yesterday. I was petting Franny and felt something on her neck. I looked quick and thought, poor old lady, you have a skin tag on your neck. Looked closer, nope, skin tags don't have legs. Now I'm grossed out. It's a tick, and a very engorged tick. I got the tweezers and started to pull. That thing did not want to come out. I finally got it out, but now I'm not sure I got the whole thing. I looked at her neck just now and there is a little brown spot, but I can't tell if it's a scab or part of the tick.
I don't have experience with ticks, so what should I do?
