Hello,i always love pure bred dogs.But im thinking about my two pets,one is a Rottweiler and the other one is a German shepherd.Is this a good idea?or should i just keep them that way?

There are already a lot of rottie/shepherd mixes out there. It is not recommended to deliberately make more, as the results can be somewhat unpredictable. For now, just enjoy the best traits of each of the two breeds you currently have.

Thanks for the advice.I really think twice about this.
