tracking dogs getting better with age?
So, what does everyone think about dogs getting better at tracking as they get older? Has anyone ever worked a tracking dog from a young age to old, continuously in a competitive environment (FH, VST, TDX, StP, etc)?
My gut says any dog that spends close to a decade in a tracking/scent sports would be quite good, even if entering the early phases of physical decline.
Does anyone have any personal experience?
Have there been any really old dogs competing in the National or World Championships for IPO-FH?
