Questions
How much should my puppy weigh at 8 weeks?
It depends on the size it will be. A typical puppy is about 23% to 28% of its grown weight at 8 weeks if it's toy to medium, about 19% if it's large and about 13% if it's giant.
Why is my puppy's range so wide?
A young puppy has most of its growing still to do, so small differences now become big ones later. Weigh again in a few weeks and the range narrows.
What if my puppy is ahead of or behind the chart?
A puppy ahead of or behind the chart is often just a bigger or smaller dog of its group. Try the next size group up or down. Your vet can tell you how your puppy is growing.
