The common one is "ticks", so don't be caught, because ticks may contain infectious pathogens. After being stimulated, ticks will drill deeper into the body and release tick saliva at an increased dose. In another case, it is completely pulled out (the head is not broken), and it will be found that it has bitten a small piece of animal meat in its mouth. You can imagine how much pain this will bring to animals.
It is recommended to go to the veterinary clinic, where there will be special anthelmintic drugs that can be sprinkled on the body to achieve the purpose of expelling insects and killing insects.
