A 6-year-old neutered Cavalier King Charles spaniel was presented with a 2-week history of difficulty climbing stairs and jumping into the car.
The Cavalier King Charles spaniel (CKCS) had a previous diagnosis of a grade III/VI left systolic heart murmur.
The heart murmur as previously described was detected. Instability in the left stifle was also noted. The remainder of the examination was unremarkable.
