Sometimes Breeding dont go as you wish

We have taken the decission to Castrate our Isabella GSD Lilac because she dont want to mate and she also got 5 this year. Last year we tried to bread her, but she did not get pregnant because of an bacteria infection. After treatment and alot of testing we realized that we where out of time. Breeding is very costly and not always easy and sometimes you just have to let go. This year we will not have any puppies of our own.
