Puppy's littermate has distemper. Is my vaccinated puppy safe?

Updated On September 23rd, 2025

Pet's info: Dog | Morkie | Male | 2 months and 8 days old | 3 lbs

I am going to purchase a puppy. A few days before the puppy was ready to pick up at 10 weeks old, the breeder called and said one of the puppies was sick, he did not want to sell anyone a sick puppy and the pick up date was to be delayed. It turns out the sick puppy, (not the puppy I chose) has distemper. This breeder has been very honest with me assuring all his puppies have had 2 distemper/parvo and wormings, none of the other puppies are sick or showing any symptoms. Are the others ok?

Yes, if they had the vaccine (first and second dose) it is unlikely that they contracted any distemper so they are going to be ok. You can of course have the puppy you want checked by a veterinarian before picking her/him up.
