Dogs can catch A. streptococcal sore throat, also known as strep throat, from humans in the household, according to WebMD. Dogs rarely pass strep throat to humans, but it does occasionally happen. One of the best ways to prevent strep throat from recurring is to treat every member of the household for sore throat, even dogs and cats.
The most common symptom associated with strep throat in dogs is a mild sore throat. It's often hard to tell if a dog has a sore throat because its symptoms are not very noticeable. If a dog has severe pain in its throat it will typically gag, cough, have a fever and express signs of being in pain.
There are numerous causes of sore throat in dogs aside from strep throat, including chronic tonsillitis and primary bacterial tonsillitis. Sore throats in dogs are also a sign that a dog might have a serious medical condition such as distemper, parvovirus, pseudorabies or herpes virus.
Dogs commonly have a sore throat combined with multiple other symptoms and they rarely have an isolated sore throat. If a dog experiences symptoms of a sore throat and additional symptoms, it's important to take it to a veterinarian for proper diagnosis and treatment. Often times a veterinarian will suggest feeding a dog canned food mixed with water to help it go down easier until the dog begins to feel better.
