In this episode, Hank finally decides to make his beloved dog, Ladybird, a mommy. Conveniently, his boss can help. However, Ladybird cannot give birth due to a contrived reason that is suppose to make a connection between her and Hank. The rest of the episode mostly focuses on Hank being a hypocrite; willing to do things on Ladybird that he previously called: unethical. And there a throwaway scene that further shows Hank as a homophone; complete with stereotypical gay guys. At the end, Hank reveals the only reason why he is doing all this is because he wants to give Bobby a brother. He was able to make Bobby when Ladybird arrived. He could've gotten another puppy instead, but then there wouldn't be a plot for this episode.
And as for the B-story, Dale becomes a bounty hunter. Samus Aran, he isn't. He took a weak BS four hour course, makes obvious mistakes, and has an anticlimactic ending with him watching TV with a carbon copy of himself. Although this does play into the main plot, it is contrived nonetheless.
The same is true with the C-plot featuring Bill and Bobby.
I've seen better episodes of King of the Hill, and I've seen worse. This episode is just meh.
