Hello! I was wondering if anybody might be able to help me estimate my puppy's adult weight, based on her puppy weight.

Here is the data I have on her weight:

10 weeks: 5lbs
15 weeks: 7.4
19 weeks: 9

So almost double since 10 weeks! Seems o be growing quickly, no? I haven't a clue what is normal growth rate for cavs. Any input would be greatly appreciated!
