When is it safe to breed my female rott

Question
My kids were given a two rott puppies (male and female from different litters) for their birthdays by family members. I know that once the male gets a little older he's going to want to mount our female. I would like to get one good litter from them before I fix them so when is it safe for my female to have her first litter.

Answer
Hi jose;
I would never breed the first season. It is better to wait for the dog's second season, for her health.
A dog is not really fully grown up until they are about 18 months old. they are still in the formation stage, their muscle structure, organs etc.
Unless you have 2 dogs from very good pedegrees, and have xrays of the mothers and the sires, it would be advisable not to breed them. there are so many health problems that can come up later on, that will cost you an arm and a leg in Vet bills. Hip Dysplasia is a vert real risk, and if either of the parents have the gene, the puppies will inherit it.
You should only breed if the mixing of the two bloodlines will impove the breed.
Anything else, and you are just producing puppies that can be mistreated or abandoned.
Allergies are also passed on to an extent.
It DO$ES NOT make a female healthier to let her have one litter before she is spayed, in fact, it increases her chances of having breast cancer when she is a little older to let her have puppies at all.
My son raises rotties, and he has a wonderful bloodline, but he is very selective of breeding. He produces good dogs that he sells for hundreds of dollars, and people who get them will not abuse or abandon them.
Also, if either or both came from a pet store, then they are certainly from a puppy mill. the breeding is so terrible in those places. The creeps who have these places breed as fast as a female can breed, until she is worn out, then they take them out and club them in the head. they are starved. They only feed enough to barely keep the dogs alive, and when they sell them to pet stores, they arrive in terrible condidion. the pet stores have to keep them and feed and care for them until they look presentable to sell. then they tag on a higher price than you would pay for a really good breed, from a selective breeding program.
If they come from stock like that, you should not breed them under any circumstances.
You will save yourself a lot of trouble and grief, if at about 4 to 5 months of age, you have the female spayed and the male neutered.
