I'm sure this has been asked before but I would really like to get these 2 ticks off my pup now. What is the best way? It is right under his neck and he won't be still. I dabbed some vinegar on it hoping it would back out. Not for sure if it did Rosco won't be still. Any suggestions. How much do they have to weigh to have tick medication? He is 2.4 oz. Also the vet said to bathe them with Dawn dishwashing liquid for fleas does that work on ticks too?
