Frequent petting of dogs may transmit parasites, but the chance of infection is relatively small, and it is only possible to be infected by close contact. If you bathe your dog on time and deworm your dog regularly, you will not be infected with parasites. Therefore, you should pay more attention to your dog's hygiene and do not take your dog to places where there are many mosquitoes. You should also pay attention to the hygiene at home. Please clean and disinfect regularly to avoid the growth of bacteria.
