Good Morning and welcome. I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
Congratulations on the puppies! Wow! That is a lot of puppues for poor Clieo to take care of....
It is very important that each puppy get some of Clieo's first milk within 18 hrs so if some have not gotten this, then you may have to milk her out and then bottle feed them. With this many puppies, you may have to switch puppies and bottle feed some of them after you are sure that each has gotten some of the mother's milk. Go to the pet store and purchase Esbilac which is a puppy milk replacer and bottle feed the hungry ones every 2-3 hrs. Switch puppies so Clieo can feed each one.
Since you say that some are falling off, these may be the ones to bottle feed.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please Reply so I can clarify for you
Sincerely, Dr. Loretta
