How long before my dog can go around other that just had puppies?

It is generally recommended to wait at least 6-8 weeks after a dog has had puppies before allowing them to go around other dogs. This is because both the mother dog and her puppies are highly susceptible to infection during this time. The puppies' immune systems are still developing, and they are more likely to catch diseases from other dogs. Additionally, the mother dog may be protective of her puppies and may become aggressive towards other dogs.

Here are some specific reasons why it is important to keep a mother dog and her puppies away from other dogs:

* Parvovirus: This is a highly contagious virus that can cause severe vomiting and diarrhea in dogs. It is especially dangerous for puppies, and can even be fatal.

* Canine distemper: This is another highly contagious virus that can cause a variety of symptoms, including respiratory problems, vomiting, diarrhea, and seizures. It can also be fatal.

* Leptospirosis: This is a bacterial infection that can cause a variety of symptoms, including fever, vomiting, diarrhea, and kidney failure. It can also be fatal.

In addition to these specific diseases, a mother dog and her puppies can also catch a variety of other infections from other dogs, such as fleas, ticks, and worms.

It is important to note that even if a mother dog has been vaccinated, her puppies may not be fully protected. This is because puppies' immune systems are still developing, and they may not be able to produce enough antibodies to protect themselves from infection.

For all of these reasons, it is important to keep a mother dog and her puppies away from other dogs for at least 6-8 weeks. This will help to protect both the mother dog and her puppies from infection.
