At what age can you breed a female rottweiler?

For all dogs the best time to breed them is when they are 1 and 1/2 years old or when they are 2 years old. 2 years old is a better time to breed a female as they will have gone into about 4 times, and they are not as young. When a dog is younger and is bred, they have a greater chance of losing the litter and/or losing their life.
