What happens if you directly pull off a tick from a dog's body?

If you directly pull off a tick from a dog's body, it can cause the tick's mouthparts to break off inside the skin, leading to inflammation, ulceration, and increased body temperature in the dog. It is generally recommended to use alcohol to wipe the tick's body immediately, wait for the tick to become numb and release its mouthparts, and then gently use tweezers to remove the tick from the dog's body. If the owner is unsure of how to operate, it is advised to seek help from a veterinarian. Additionally, it is recommended for owners to regularly apply insecticides to their dogs for prevention and avoid taking their dogs to places with tall grass.

After a tick attaches to a dog, it sucks the dog's blood and deeply inserts its mouthparts into the dog's skin. If the tick is pulled off directly, it is easy to cause the tick's mouthparts to break off inside the skin, triggering severe infections, causing itching, ulceration, inflammation, and redness and swelling. If subsequent severe infections occur, such as bacteremia or sepsis, it is likely to cause death in the dog.
After a tick sucks blood, its body swells up and the mouthparts are embedded in the skin. If the tick is not removed in time, it may cause secondary infections, leading to skin redness, swelling, and ulceration. Secondly, ticks can transmit blood parasites such as Babesia and cause anemia in dogs. Additionally, some ticks release large amounts of neurotoxins, causing muscle paralysis in dogs, which can lead to respiratory failure and death.
It is recommended for owners to handle the tick promptly after discovering it on their dog. For visible tick adults on the dog's body, alcohol or medication can be applied to the tick's surface to numb it, and then tweezers can be used to remove it without leaving the mouthparts in the skin. Meanwhile, use parasite control drugs containing non-proprietary ingredients such as flonicamid and methoprene for whole-body parasite prevention, and thoroughly disinfect the dog's living environment.
If the owner is unsure of how to handle the tick at home, take the dog to a pet hospital for treatment. After removing the tick, timely inflammation and disinfection of the affected area are necessary to prevent secondary infections.
