Dakota is 2 days shy of 12 weeks. Last night he weighed in at 19.5 lbs. That in itself isn't surprising, but it is a 4 lb gain in 5 days!! He eats about the correct amount. I just switched him to Eukanuba from Sciece Diet; he gets an occasional treat when training. He isn't at all fat; I can feel all of his ribs--he's just all long legs and big feet! Is this unusual?
