Ok, I am now getting a little worried about Jetta. She is gaining size...but she is not gaining bulk..her ribs still show, her hips at times show (depends on if she just got taller or not) and she doesn't get excited about food. She eats less than a cup of food...usually about 1/2 cup of food a day...and that's a struggle. What are some tips on getting a puppy who doesn't want to eat to eat? I just feel she needs to eat a bit more.
