Am I the only one that does this? (breeding)

So, I don't like dogs above 600 TP. That is just my opinion. So, I purposely breed my dogs to make sure that their puppies are under 600TP. Sometimes I have dogs above that, but I really don't enjoy it.

Maybe that makes me lazy, IDK, but if I'm spending 2 weeks on the SAME dog I get really bored and start to lose interest in Ala xD;

So am I the only one that does this/gets bored?
