less cautious Niko is now 1yr and 5monts. I weighed him today and he is exactly 6lbs. He seems so tiny. I could not imagine a full grown that is half his size. Although he has a very big dog attitude, he is very fragile. My vet told me he would mature to 4 1/2 pounds. He is bigger, however, I give him many treats. Initially I think I was so concerned about size that i didn't want to overfeed. Now I still don't overfeed but I am less cautious about weight gain and allow him to experiment with many foods. I've found out, he likes everything but pretzels. : |
