Pet Dog May Cause Recurrent Strep Throat

In rare situations, strep throat infection bounces repeatedly among all family members. In such situations, the family's pet dog may be the carrier for strep that may cause such recurrent strep infections among the children and parents. See references below.

Fortunately, in the vast majority of situations, the pet dog has no role in recurrent strep throat infections. Indeed, many healthcare professionals are in fact skeptical that the dog has any role.

Personally, I'm a semi-skeptic, but open-minded to the possibility.

In any case, should the dog become a suspect, the vet should obtain cultures from not only the tonsils, but also the eyes and anus. Should cultures come back positive to human strep, the dog should be given antibiotics.

Otherwise, interventions that may help when a family suffers from recurrent strep throat include antibiotics given to all family members simultaneously as well as performing tonsillectomy in the family member who seems to get strep throat the most which often breaks this distressing intra-familial cycle.
