Puppies not nursing or taking formula. How to ensure nutrition?

Here is a link which may help: https://www.petcoach.co/article/orphaned-puppies-how-to-raise-them/ I also recommend to have Lacey spayed when the puppies are 12 weeks old. There are many health and behavioral benefits: https://www.petcoach.co/article/spaying-ovariohysterectomy-the-benefits-in-dogs/ I hope this helps.

Weigh the puppy daily to make sure it's gaining weight. If it's not, start supplementing the puppy with puppy formula. I will put a link below on how to do this. Best of luck. https://www.petcoach.co/article/orphaned-puppies-how-to-raise-them/

At 4 weeks they are still fully nursing so you will have to supplement for forumla. 4 weeks is s good time to start introducing puppy food. You can start with canned food with some water added to make it thinner and softer and place a small amount in his mouth to get him interested in it. Once he starts doing well with that you can decrease the amount of water and start soaking dry food to add to the canned until he is fully weaned. They do make a supplement called Nutrical that is helpful for young puppies that are weaned but not eating great

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.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Those puppies look very healthy. The only way to make sure they are getting enough milk is to weigh the puppies every day and make sure the puppies are gaining weight. Neonatal puppies should have a weight gain of 5-10% of birth weight daily --they may lose a little the first 24 hours, but after that we need to see this weight gain. If they are not gaining at that level, they need to be evaluated, and if otherwise normal, supplemented with formula and tube feeding to achieve this weight gain. Sounds like everything is going great with Juliet and the puppies. Remember to feed Juliet puppy food during this time because her nutritional requirements are very high during lactation. Good luck

Nursing puppies takes a lot of energy from a dog, and Angel should be fed a puppy formulated food to give her the increased calories, protein, and calcium she needs to be healthy. You don't want her to gain weight unless she is quite thin, bug she absolutely needs the puppy food. Make sure she is up to date on her deworming treatments as well, as that can cause weight loss in dogs.

Mom should have enough milk for all five puppies and you should not need to hand feed them formula. If you think they are not getting enough milk, have it verified by your vet. In that case you can supplement with puppy formula while they are still feeding from mom.
