I just want my Khloe to be a healthy weight. I was in the vet this morning picking up heartworm meds for my other girl, Kirby. I was looking at their shelf and most of their products said 5 pounds and over. I don't want Khloe to be under 5 pounds. I know she is still a puppy but she seems so small at three pounds. I can't imagine that size dog as an adult. I would be afraid of medical procedures on an extra tiny dog.
