I took Maggie to a Pet Expo this past weekend for a "crowd experience". While there many people with labs came up to me and we compared ages, ect. Well these labs were about 7 mos. old and 3-4 times the size of Maggie who is 4 mos. And 3-4 times larger as in height and weight. Do puppys really grow that much in such a short period of time? (Or could it be I have a dreaded "mini-lab"?!! :o) Maggie only weighs about 26lbs. She isn't an eater. As a matter of fact the vet has me adding chicken baby food to her dry "Blue Buffalo" brand to try to get some weight on her. She liked Iams but didn't gain any weight and totally refused to go near Innova. ???
