If there is a major tick infestation, you should use rubbing alcohol or isopropyl. First, pull out the ticks with your tweezers and dip them in rubbing alcohol. This will kill them almost immediately and reduce contamination.
Be prepared to pull hard to remove all the ticks. It may draw blood too. In some cases, doctors would ask you to rotate the tweezers 360 degrees to remove the big ticks. By rotating it, you would loosen the grip and remove it right from the mouth.
It is always important to remove ticks from the mouth. Ticks belong to the spider family or the Arachnids, which means that their mouth is largely of the chelicerae and hypostome. But unlike the spider’s chelicerae, which is soft, the tick’s chelicerae and hypostome are hard, barbed and pointing straight again. It effectively pinches the skin and pierces through it. The chelicerae work like little saws but since ticks have an antiseptic substance in their saliva, dogs don’t feel it going in, they do feel it coming out, especially if it’s forced out.
The mouth has all the disease-causing pathogens. If the mouth remains stuck to your dog, it disintegrates and fall off within a few days. However, it does expose your dog to dangerous pathogens for longer. If there are too many ticks, please consult your doctor and get them removed professionally.
Be careful if the ticks are on sensitive places like the eyes, ears or groin. Consult your doctor, if it’s causing your dog discomfort when you take them out.
Lastly, rubbing alcohol is a good alternative you have an older dog that is less likely to pounce and make a mess. It is poisonous to dogs and even small amounts of it can get absorbed through the skin and make your dog tipsy. The smaller your dog, the more dangerous it is. You should never rub it against their skin. Rather dip the ticks in rubbing alcohol after you safely detach them.
