There is something on my dog's neck with a picture on it.

Have you got any pictures? You can't tell by the description. thank you

I saw this kind of dog pox, the scientific name is tick (pí), which is attached to warm-blooded vertebrates and sucks blood. It is an important vector for many infectious diseases of human beings and lower animals. Dog beans are generally parasitic in grass, so it is recommended not to go to places with trees and humidity.

Solution:

1, alcohol can be applied to the body to relax or the head of dead dog beans. After a few minutes, take out the tick with pointed tweezers, hold the tick in your mouth and pull it out quickly. 2. Flea spray can be sprayed on the infected part, and the dog beans will die and can be removed the next day. Spray flea spray on the infected area regularly to keep the area clean. 3. It is not advisable to forcibly remove the "dog beans" bitten on the skin. You can drop a drop of tincture of iodine, alcohol or ether on it, or bake it with a cigarette to make the dog bean fall off automatically, or you can prick its abdomen with a needle to make it fall off automatically. 4. Applying soapy water or sodium bicarbonate to the wound can relieve pain and reduce swelling.
