Hi Karen,
No, there is nothing that I can think of lately that has changed in his life.

He has 2 acres of land to run around all day long during the day, so he gets plenty of exercise. I also regularly play with him.

He seems just like he always has, really no personality changes. If I leave him out at night, he usually tires himself out and he can be found in his cage out cold. The only problem is that when he is out barking everybody else is trying to go to sleep.

Everybody in my family has dog allergies, so he really can't be kept in the house at night.
