I think Alexa is going to be a smaller dog, right now at 13 weeks shes 7.2kg. What did your puppy weight at this tiime? Also pictures of them around this age would be great (I love seeing other bc's at this age)
Kona is on the smaller side too, he was one of the smaller pups out of his litter mates. I think Kona weighed just a little less at 13 weeks, (but very close) at 15 pounds (6.8 kg). He's about 19-20 pounds now.
