We took our puppy with us to the ice cream shop today and there was another couple with a 12 week old boxer; ours is 9 weeks now. Their puppy was HUGE in comparison to ours. I mean she had to be 4-5 times the size of ours, but only three weeks older! Last week, at 8 weeks old, our coco was 6.6 pounds. What did your puppy's weigh around this age?? I just wonder if she's abnormally small, or maybe there is a major growth spurt between now and 12 weeks? Or if I will have a tiny dog when she's grown?! It was CRAZY to see the size difference!
