If a dog gets canine distemper without going out, it may be that the dog itself carries the canine distemper virus or the owner is exposed to the canine distemper virus when he goes out and then comes into contact with his own dog after returning home, resulting in indirect infection of the dog. Generally, puppies There were maternal antibodies two months ago, but after two months, the maternal antibodies decrease and the dog is more susceptible to canine distemper. Therefore, it is best to vaccinate the dog in time. Do not take a bath or take the dog out without vaccination. When other dogs play, owners need to wash their hands and disinfect their hands after going out and coming into contact with dogs. This can reduce the possibility of dogs being infected with canine distemper.
