I am 70 and single, but in good health, active and walk daily with Ozzie. We also do long hikes when we go to doggie camp in the summer (2-3 hours or more on mountain trails.) I know that Ozzie would love a little buddy and I have been thinking about adding a mini doodle 25 pounds or so. Ozzie is very well trained as would be the new doggie. I just can't seem to pull the trigger on this. I keep doing the math and worrying about finding myself in a situation where newest doggie might have to be rehomed. I know that the future is unpredictable and one shouldn't try and predict what is going to happen in 10-15 years (average life span of my genetic pool!). Has anyone else faced this question? Any input might help me decide one way or the other.
