No longer the speedster she once was, Nala is aging gracefully as she turns 50 in human years.  She can still out run me but in another year or two I expect to gain the advantage.  She remains gentle and independent, behaving more like a cat than a dog.  I am going to try and persuade Maya to reshoot a photo that I took when Nala was just a puppy.  Although she is much larger now, Maya is plenty strong enough to pick her up and I think the grass in Mattison field is just the right height. Stay tuned.
