I can't remember everyone's weights when they were puppies. Shorty was 7lbs when I brought him home, he was probably around eight weeks old, now he is 49lbs. Freyja was 29lbs at around ten weeks, that is when I brought her home. She is not done growing but is now 120lbs and 14 months old.
I've estimated that Alva weighed around 5 kg when she was 8 weeks old. I did not have a scale back then. I weighed her later when she was 10 weeks and she weighed 6.5 kg. Her adult weight is 22 -23 kg. Alva is a rough collie.
Sancho was already older when we got him he was around half year and had ca. 12 kg (he was underweight). Now he's ca. 40kg.
Teo (Boxer) was around 6-7 kg at the age of around 8-9 weeks, if I remember right.
As an adult he was between 40-45 kg depending on how much training he had (more work-> more muscles-> more weight).
