My puppy is 2.3 at 10 weeks although she looks awefully tiny and nobody believes me that she weighs that. I know other chis that weigh under 3 lbs. and look bigger than she is. Do they usually gain about the same number of ounces each week or does it vary? She supposed to weight 4 1/2 -5 lbs. I don't really care how much she will weigh full grown I was just wondering if this is a normal weight for her age. What do or did your puppies weight at 10 weeks? Thanks.
