Well I just came home from the vet with Oliver, lol...He needed to get his rabies shot, and he weighed in at 29 3/4 lbs. !!!!!!....He gained 8 1/2 lbs in 2 weeks. !!!!!....The vet said he is not fat, just perfect, lol, I cannot imagine how big he is going to be...Well he is 4 mos old, so I guess double the weight and add ten lbs? I believe that is what you guys said, so he should be 70 lbs...OMG, I look at him now and can't see that, lol...But I am feeding him 2 cups of food in the am, & 2 cups in pm, with some treats in between. The Vet said I should feed him a little more, that at this age he is an eating machine...He gobbles down the 2 cups in no time flat, so maybe I will give him a little more with each feeding...I went to the food group here, and lots of ideas there, so I guess it is like pick and choose and try it with Ollie. I am in the process of taking him off of Purina Puppy Chow something and on to the Canidae that I have used for my other dogs...Great food, the others did wonderful on it, so I am doing 50/50/ at this point....Do you guys think I should just keep food as I am doing or increase it gradually?...I am very confused with this, never had a puppy grow so fast, lol, but he is sooo cute...Oh and we moved his crate in our room, and no more getting up at night, he has slept thru the night the last 2 nights.!!!!!!...He got up at 6:15 am, but that is fine with us from 11 the night before...Ah the joys of puppyhood, lol....Cheryl
