[Deuce]

Woah, it sounds like she is just trying to make you have a heart attack and die!
Goodness, I work full time as well and my pup has made it to 7 months old and is perfectly healthy (knocks on wood) I just set up my kitchen so he would be as comfortable as possible with room to move around and plenty of toys to play with, plus a doggy bed and his crate. I put up a baby gate so he cant wander out and get into anything he shouldn't, and I leave food and fresh water down and now a fan on the counter blowing down so he doesn't get hot (no a/c, boo) I put a pee pad down so he can go potty while I'm not at home, and just an FYI no puppy will hold their pee/poo long enough to die from it.
Ps. why is this woman hating on you so much? Is she trying to scare you into giving her your puppy? Geeze Louise!
