Happy 15th birthday, Alex! He looks quite good for his age. I think the older ones just have to be monitored a bit more closely for changes in their weight. My Marco is probably about 15 or 16 and I have to consistently feed him more than my other Bs to keep him in good weight. Thank goodness he's a hearty eater and will finish whatever I put in front of him 98% of the time.
Pat, your guy looks excellent for 16! He looks much younger. Careful breeding sure makes a big difference. No one who sees Ellie believes me when I say she's 12.
