I'm not actually sure sorry
No , the female reproductive organs have been surgically removed .
When they have been weaned, meaning, no longer suckling for the mother's breasts for food. 8 weeks - no less.
All Female dogs can have puppies, but only if that havn't been fixed. I don;t completely understand your question but by 'may' I think you might have meant 'many'.
Men should not use steroids when trying to get a female pregnant unless they are medically necessary and have been prescribed by a doctor.
If the female is in her cycle now she will definitely get pregnant and the puppies might not make it. Your dog WILL NOT make it. I am sorry it has happened to my dog. The puppies did not make and either did the mother.
It probably is just because he is protecting the puppies. Usually it is the female's job to do so. If the puppies are still pretty young, then this is understandable.
Yes
No, not unless the other dogs have something and the puppies have not yet been vaccinated. It is time to vaccinate at about 6 weeks old for dogs and cats. This is a good time to spay and neuter the pups also.
Due to the high incidence of parasitism in puppies and the risks posed to humans by hookworms and roundworms, the Center for Disease Control recommends that puppies be started on a preventative deworming schedule at 2 weeks of age and continued every 2 weeks until they are at least 8 weeks of age. Some veterinarians recommend continuing this deworming program until a pup is 12 weeks of age or is started on a monthly heartworm preventative that also treats hookworms and roundworms. For puppies who have not been dewormed regularly starting from 2 weeks of age, fecal examination to determine their infection status and then appropriate deworming treatments should be performed. Your veterinarian is he best source of information on deworming your puppies and should always be involved in setting up a deworming program.
No, if you watch previews for next weeks show they are playing with the new puppies in the basement. The last 2 weeks shows have just been during the day when they are at school
Most breeders will charge around £50 more for female puppies than males. Although both genders make great pets, females are worth more because they can produce puppies. Other breeders will charge the same for both males and females.
A "fixed dog" can no longer breed puppies. The male will have had either a vasectomy or been neutered; the female will have had her ovaries and uterus removed.
