I just switched my puppy from Nutro to Royal Canin Puppy Formula (per vet recommedation) and she seems to be eating less lately. She loves the food but only eats once a day but before she would constantly eat all day. Now when I pick her up she feels like she weighs a ton (she currently weighs 4.3 lbs). Is the Nutro making her stay full longer?
This is my 1st time posting to this site.

I am truly amazed by all the Yorkie lovers out there. This is the 1st time I've ever owned a puppy and I am loving it!!!
