I can definitely notice a different in her shape. She looks much more well put together and nicer muscle tone.
Her feet... WOW. They are extremely short in that first picture. Her feet looks 10x more healthy now.
To me, in that first video, she looks to be trotting shorter in her stride, and it would make sense since her feet were awfully short and probably not very comfortable for her to move on.
The second video, she looks more relaxed and to be stretching her stride more.
...he's so kissable, huggable, loveable, unbelievable...
