a bitch who's just whelped shouldn't be around another F while she's nursing, nor should any other dogs - of any
sex, intact or not - be in the same room with her newborn pups - with or without their mother being present.
Dam & pups need a room of their own, & if the only room with a solid door is Ur bedroom, that's where they need to be.
Mom-dog should be walked solo, potty solo, etc. // Until the pups are at least 6-WO, they should be kept entirely away from the other dogs in the household.
here is a good source for advice on caring for Mom & her pups - https://vcahospitals.com/know-your-p...ewborn-puppies
Along with spaying Mom, i strongly encourage neutering Dad, & if the other F is intact, please spay her, too.
Intact Fs can very-rarely share the same space safely - F dogs, even spayed Fs, can fight ferociously & inflict horrific wounds on one another. M dogs in the same home rarely do the same level of damage to one another as Fs will do.
A mother with newborns is very protective, & her hormones are running high. The more times she is made to feel threatened by the other F or other dogs, the less likely they will ever
get along again, even after the pups leave - AT -8-WEEKS-OLD.
I hope U do realize that U will be caring for the litter for 2 solid months?
And when the pups begin sampling solid food, Mom-dog will stop eating their poop - this starts around 4.5 to 5-WO, so U will be cleaning up puppy-poop for 3 weeks B4 the pups are ready to depart.
Neutering everybody ensures that this won't happen again, & that Dad won't go walkabout to find other Fs to impregnate, either.
