My bitch recently had a litter of 3 pups unfortunately 2 passed and the last one is staying with the breeder for a week as he started going down hill loosing weight  even though we were getting him to feed hourly he's now getting better (being tube fed) how can I keep the bitch producing milk for his return thank you.

...You start by saying... 'My bitch'...you then say 'staying with the breeder'....confused??

The bitch & puppy need to stay together...if not she will definitely loose her milk, especially after a week.
