Answer
Hi Ami. You said she whelped her first litter with no problems, and the pups were healthy. As long as you keep her healthy this time, I don't see there being a problem. Not saying there won't be any, but she has a good chance of repeating the first time. Don't let her get fat, don't feed her puppy food, and make sure she gets plenty of exercise. Take her to the vet if any problems arise, no matter how small. I wouldn't suggest allowing her to become pregnant on the next heat. Either have her spayed, or wait for a full year to breed her again. If I can help with anything else, let me know!
