First 24 Hours After Birth: A Checklist for Puppies, Kittens, and Calves

The first 24 hours after birth set the pattern for the whole litter. Puppies, kittens, and calves all need the same three things in the same order: warmth, colostrum, and a quiet place to nurse. Get those right, and most problems show up early enough to fix. Here is a simple checklist that works for all three, with the differences noted where they matter.

1. Warmth first

Newborns cannot keep warm on their own. Keep the whelping box, nesting box, or calf pen warm, dry, and draft free. A heat pad under half the box lets puppies move away if they get too warm. For calves, dry them with clean towels and keep them out of wind and wet bedding. A cold newborn will not nurse well, so warmth comes before feeding.

2. Colostrum within 2 hours

Colostrum is the first milk, and it carries antibodies that protect the newborn. Puppies and kittens should nurse within the first few hours. A calf should stand within 1 hour and drink colostrum within 2 hours, ideally 4 litres in the first 6 hours for a dairy calf, as your vet advises. Colostrum quality drops fast after birth, so timing matters more than volume alone. If the mother cannot feed, use a proper replacer, not cow milk for puppies and kittens, and call your vet for advice.

3. Check the navel

For calves, dip the navel in iodine soon after birth to cut the risk of infection. For puppies and kittens, check that the cord is short, clean, and not bleeding. A cord that bleeds, or a navel that swells, reddens, or smells, needs a vet check.

4. Weigh every baby, every day

Weigh each puppy, kitten, or calf on day 1, then daily for the first week. Healthy babies gain weight every day. A baby that loses weight, or does not gain for 2 days, needs a vet check, even if it looks active. Weighing is the earliest warning you have, because babies hide illness well.

5. Watch the mother too

Check the mother for bleeding, retained placenta, fever, loss of appetite, or not getting up. In cows, a placenta not passed within 24 hours needs a vet check. In dogs and cats, a foul discharge, heavy bleeding, or a mother that will not settle with her babies needs a vet check the same day. Keep her water and food close, and keep visitors away for the first days.

6. When to call the vet in the first 24 hours

• A baby that does not nurse, is cold, weak, or constantly crying.
• A baby that loses weight, or does not gain, in the first 2 days.
• A mother with heavy bleeding, bad smelling discharge, fever, or retained placenta.
• Any baby with a swollen or smelly navel, breathing trouble, or a birth injury.

Book a vet check for mother and babies within 24 to 48 hours, sooner if anything on this list applies. The first day is not the time to wait and see.
