You can keep a dog when you are pregnant, but pregnant women who keep dogs may be infected with various pathogens. So if a pregnant woman wants to keep a dog she needs to vaccinate or deworm the dog in time and pay attention to hygiene. Pregnant generally can raise a dog, but because the dog may have a variety of bacteria and parasites, if the pregnant woman and the dog often close contact may increase the chances of infection of pregnant women. If you have a dog, you need to give your dog regular vaccination or deworming medicine, give your dog a bath on time, and wash your hands in time after each contact with your dog, which can reduce the chances of infection in pregnant women. If a pregnant woman is allergic to dog hair, she should avoid keeping a dog to prevent allergic reactions such as itchy skin, rashes and breathing difficulties after regular contact with dog hair. In addition, pregnant women should regularly go to the hospital for maternity checkups during dog ownership, and pay attention to home hygiene to regularly remove the dog’s feces to prevent infections. In addition, pregnant women should avoid contact with dog bites.
