Newborn runt puppy not eating, getting cold. How can I help?

You can try supplemental feeding with dog milk replacer and keep him warm and next to the mother and others if possible. Sometimes there is an underlying medical problem with the runt and in spite of your best efforts they do not survive. Dogs and other animals have litters with several pups because there is often one or two that don’t live. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Lucky.

I would recommend taking him away from the others for feeding and hand feed a calorie rich food such as royal canin recovery or hills a/d through a syringe if he won't eat voluntarily. Try to get an earlier appointment for full health check if possible

I'm so sorry to hear about your pup. First step is to warm him up. A Heating pad set on low with the cloth cover on will work. Other types of warm packs are ok too as long as there is a towel/cloth between the heat source and the pup. Keep heating until a rectal temp of 99 is achieved. Meanwhile, rub a small amount of white karo syrup or honey on his gums to help with low blood sugar. Between these two things he will hopefully perk up within 10-20 minutes enough to take the bottle/teat. Then feed as often as he cries. DO NOT try to syringe or force food until you are sure he is swallowing well as this can cause pneumonia if he accidentally inhales a little. Side note: I know it's silly, but be sure that you have poked a hole in the nipple of the bottle (many come with no opening which is weird). Sometimes, despite these efforts, a puppy will not respond and you will need to see the emergency vet for IV bloodsugar and fluids, etc. Even then, we sometimes cannot save them and they do pass. Many times these are the runts of the liver or we suspect there is something else going on (born with a congenital organ problem). Hope this helps and best of luck to you and the baby!

Hello there! I'm sorry to hear about your runty puppy. If the mother won't feed him and you can't get him to nurse, it's unlikely that he's going to survive for very long. Sometimes, small or runty puppies have internal abnormalities that prevent them from being able to nurse properly, and these pups generally don't make it without aggressive care. I highly recommend that you bring this pup in to the vet first thing in the morning for evaluation and treatment - even if that treatment may mean humane euthanasia. Keep him warm and try to feed him warmed milk replacer at least every few hours. If he appears to be very lethargic or is having breathing difficulty, you may need to bring him to an emergency vet tonight. There is a 24-hour hospital near you - here is their information: Animal Emergency

Yes, helping her nurse every 2 hours should be adequate. I would recommend getting a kitchen gram scale and monitoring her weight daily. If she is not consistently gaining weight, you may need to start bottle feeding her to make sure she is taking in the appropriate amount of milk.

Yes! You absolutely must booster the runt a bit as it is likely getting much less nutrition than the others in the litter. Mom will neither reject the pup nor will the pup reject mom if you add additional nutritional support. This is very commonly done by breeders with smaller pups.

Considering the puppy is losing weight and failing to thrive, I would bring him into your local vet for an exam to check for any physical deformities that may be affecting his ability to nurse properly and eat, and for any potential illnesses or issues that could be causing him to not do as well. If he is able to eat with a bottle, I'd also recommend increasing his feedings if he still seems hungry, to try and keep weight on him and get him back up to speed.
