My lurcher bitch had a tick in her ear last september and only noticed when she caught it on my hand as she yelped. It was quite large but have lost my tick extractor from the vet but used my old way passed to me by an old fellow ferreter in the 70s use fairy liquid neat on to the tick leave it for 5 minutes and gently pull it off with tweezers as it looses its grip. They come off complete and quite easy
