umm shadow is, she is like 40lbs, but I dont know how much she should be, I cant campare her to happy because happys is so fine boned, she is a 21" border collie and only 25lbs, but she is not underweight she is just perfect, shadow is smaller then happy and waighs almost twice as much, but she is also heavier set then happy , but shadows weight cant come down anyway, she is lethargic , but all my other dogs are perfect in weight. now if only I was perfect in weight, for some reason I stopped practicing my dancing and have gained a littl eweight over the summer lol
