The pup seemed to have a sixth sense and knew that Richie not only had an allergy, but he also had a blood condition that didn't allow his blood to clot properly

Dogs are commonly used as “alert” animals by people with medical conditions, “seizure dogs” being probably the best known examples.

There are also “tumor sniffing dogs” who can find cancer when other more “conventional” methods fail.

Their incredible sense of smell is probably the reason why they are so successful.

Minute changes in the chemistry of their owners, unnoticed by humans would stand out like red flags of alarm, to them.
