My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today. I've been breeding rottweilers for over 20 years so I'm very familiar with puppies and their care.
Unfortunately, you are not going to like my response. Often when you bottle feed pups, the formula flows too quickly and ends up in the respiratory passage and being aspirated into the lungs leading to aspiration pneumonia. A green discharge would indicate infection in the respiratory system. It is important that you have her seen by a vet as soon as possible so that antibiotics can be given and the extent of the problem diagnosed. They may do x-rays. You should be prepared in case they determine it is unlikely the pup will survive.
If you have been seeing milk in her nostrils at all then aspiration pneumonia is a good possibility. I'd try to have her seen as soon as possible. In the meantime, keep her in an area where she can move on and off of a heating pad covered by a towel and set on low. It may help keep her warm. Be sure there are no drafts where she is and monitor her during the night. I wished there was something you could do at home, but at this point she needs antibiotics at a minimum.
