Mya is currently 4 months and weighs 2lbs. The breeder estimated that she would be around 3.5 full grown. The vet came up with this same number. The Vet said that at 4 months they have achieved 60% of their growth and she should be around 3.5. At 13.5 weeks she was 1lb 9oz, that number multiplied by two is a little over 3lbs. We'll just have to wait and see!
