Zoey may be the princess, but Spot is high maintenance. She gets doggy prozac every day along with her usual chicken and rice with vegetables. But if I fed it to her plain, she would pick out the chicken and leave the rest behind. So, I have to stir in some cottage cheese with every meal. But they also all get yogurt at the vet's recommendation, as well as a liquid vitamin supplement with every meal.
Spot is a magnificent beast, though, so it's all worth it. The vet said that she's the perfect weight, and I said "you don't even wanna know what it takes to keep her that way" haha.
