You do seem very on top of it, and committed!!
We adopted a middle-aged dog and these are the advantages I've enjoyed (vs getting a young pup)...
- he came housebroken, can easily hold it for 5-6 hours and could probably easily go from 8:30am -5:30am (although I've never tested him, as I work from home).
- he is nondestructive, doesn't chew stuff, we did not have to deal with a bitey phase
- didn't have to get up in middle of night. we are able to go to bed at 10:30 and get up at 7, no issues - we feel just fine and rested like normal
- from day 1 we could bring him for long hikes or go jogging with him
- his personality was set. I observed that he rarely barked, had a relaxed manner in the home, aloof towards strangers ... and that is exactly how he has been so far
- he already had some training. (For example his "Drop It!" is amazing, it's instant and 100%. I don't know who taught him, but kudos to them...)
That said, the young pups are so CUTE and so FUN.
It may be worth the pain. :-)
Haha, ohhh, yes.... all of those were on my list when I was shopping for a senior dog! Eventually have really decided that getting a GSD is okay. I've been so stuck on adopt-don't-shop, but these dogs are just so incredible. I suppose the adult vs puppy thing, I could go either way... just depends on how it all turns out. We shall see. But man, I am secretly hoping for that puppy, let me tell ya!
