How to weigh the puppies
- 1
Mark each puppy
Newborns look alike. Use a different colored soft collar or a dab of non-toxic marker on the coat, and add the same names here.
- 2
Weigh at birth
Record the first weight as soon as the puppy has been cleaned and has nursed. This is the baseline for everything after.
- 3
Weigh at the same times each day
Use a scale that reads in grams or ounces and a small bowl. Weigh at least once a day for the first two weeks, and more often for any weak or small puppy.
What to expect
| Age | What the weight should do |
|---|---|
| First 24 hours | Little change. A small dip can happen before nursing is established |
| Day 2 onward | Steady gain every day |
| About 10–14 days | Birth weight has roughly doubled |
Call your vet now if…
- A puppy loses weight, or has not gained after a full day.
- A puppy is cold, limp, crying constantly or will not nurse.
- One puppy is falling steadily behind the rest of the litter.
Questions
Frequently asked questions
How often should I weigh newborn puppies?
Weigh each puppy at birth, then at least once a day for the first two weeks, at the same time each day. Many breeders weigh twice a day in the first few days, especially for small or weak puppies.
How much should a newborn puppy gain?
Healthy puppies gain weight every day. Birth weight roughly doubles by about 10 to 14 days. Your vet can give you a target for her breed and size.
Is it normal for a puppy to lose weight?
A small dip in the first 24 hours can happen before nursing is established. After that, a puppy that loses weight or does not gain over a day needs checking by a vet the same day.
What should I weigh them on?
A kitchen or postal scale that reads in grams or ounces, with a small lined bowl. Zero the scale with the bowl on it, and weigh each puppy the same way every time.
Why is one puppy smaller than the others?
Litters vary, and the smallest puppy is often a runt. What matters is the trend: a small puppy that gains steadily is usually fine, and one that falls behind needs help from your vet.
