I always have that same feeling at one time or another with puppies. You know what they say: "There's a puppy in the house. You've let the devil in to play!"
We had two in the house at one time once...one was 24 wks, I think, and the other was 16 wks.
Now
that was a trip and a half!
But I do
remember it fondly!
Seriously, though, just gird up your patience and search for a solution that'll get you through to that time when you find yourself thinking, "Wow, it's been a long time since he's done that!"
