Hello all. Took my boy for his one year check up and boosters and vet told me he has a level 2 heart murmur. He's showing no other signs of heart disease or illness- he's generally very healthy and energetic, has a pretty active life, not overweight and has no other health problems at all. Vet advice was to monitor with regular check ups, keep him fairly lean and active and escalate if he does show any sign of illness or if it seems worse at his check ups. This seems sensible to me- doesn't seem much point doing a lot of diagnostic work at this stage when he isn't ill and it might never cause many issues, but being aware and focused on keeping him as healthy as possible seems sensible. Anyone else had this and have any different views? Am I being overly complacent?
