At 9 weeks Biscuit was approx 3.2kg and at 14 weeks was 5.2kg, so not much different to Milo. At 16 weeks he is approx 5.8kg. Biscuit doesn't feel tubby and I can still feel his ribs easily. However, he has a long body and shorter legs at the moment - 10" tall, so I don't want him to get too heavy for his legs!! Approx how tall is Milo? I have only just increased Biscuit's raw food to 300g a day and he is gaining approx 300g a week. I am going to take him to the nurse after Xmas for a weigh-in and opinion there. Biscuit is getting more exercise and probably has a 30 min walk in the morning and a shorter one later in the day. He follows me everywhere when he's not sleeping, so that must count too!
