50-65 days
Usually a father dog does not know his pups
Yes as long as its not storming out, dogs are fine
she might
dog empties while eating
Your gonna have to feed the pups yourself if you don't your pups will die. If the dogs breast are swollen then your dog is sick.
you wont know for sure. ask your vet.
Till they die. or until your dog eats them.
I think it is about 10 months...
Wait until she has weaned her puppies (about 6 to 8 weeks).
The larger the dog the larger the litter
no if you have 2 females and ones going to have pups the other female will mate (if she can) and then they will share pups i know this as it has just happened with my dogs
