Before you can enter a life stage record for your puppy, you need to know some key pieces of data:
- the age of your puppy in weeks, and
- the expected mature weight of your puppy
We know our puppy is approx. 5 weeks old and the expected mature weight for a female border collie at 16 months of age based on the average of smallest and largest individuals is 15.5 kg [(12 + 19) / 2].
If you don’t know the weight of the parents then calculate the breed average.
