Aw! They do grow so fast. I have to say Diesel never had that puppy bark which was sad. Maybe for like a day but he has a very deep bark now. You'd think he was a full size Doberman if you didn't see him haha.
Not sure when Amy first started barking, but getting her at 8 weeks old...day3 she learned how to puppy whine.
- and this was to get up on the bed at night, with my teenage son...LOL...and it worked, for her
