How long it takes for a puppy to suck milk after birth depends on the situation:

1. After the naturally born puppy is born, it can be started when the mother dog licks it and makes a cry. After feeding, generally 1 to 2 hours after birth, they will actively look for nipples to drink milk. At this time, the dirt in the puppy's mouth has been licked clean by the female dog, and it can breathe normally, so there will be no problem in drinking milk. When the cry does not appear, blind feeding may cause choking to death because the amniotic fluid may not be spit out from the puppy's throat.

2. If it is a cut-up puppy, it may take about 2 to 3 hours to drink milk. Because the puppies are cut out manually to help clear the amniotic fluid from their mouths and respiratory tracts. This process does not involve vaginal squeezing, so the recovery time is relatively slow. If some puppies do not respond to milk, it is likely that they will not eat and need artificial supplementary feeding.

What should be paid attention to when feeding newborn puppies:

1. The owner should let the newborn puppy lie next to the mother dog so that it can suck milk. If there are many puppies in one litter, the last puppy (usually thin and weak) should be placed on the last two pairs of teats to suck. After repeated several times, each puppy will have a fixed teat.

2. Be careful about breastfeeding and supplementing milk. Newborn puppies have not yet produced antibodies in their bodies. The mother dog will secrete a large amount of breast milk rich in various antibodies to enable the puppies to gain disease resistance. Therefore, it is best to let the newborn dogs eat enough colostrum within 1 hour. Puppies get colostrum.

3. When the puppy gets a little older, the breast milk is not enough to feed it. At this time, it needs to supplement the milk appropriately. The amount of milk should be enough to feed the puppy until it is full. It is best to use special dog milk powder and avoid feeding milk to puppies, because the gastrointestinal function of puppies is very poor at this time and can easily cause diarrhea. Boil and sterilize the dog's milk before feeding it with a bottle. The appropriate temperature is around 27-30 degrees.
