Man,14 years was a good run,its never easy when the day comes,had one retriever that made it 15yrs,then 12yrs and 10yrs,last one was 18months,even then my heart was broke as we were bonded in that short time,today my boy is 5yrs and already dreading the day when its time.
Hopefully you have a young pup to ease the pain,it helps.
