Mr. Fourpaws

Bat makes a new friend in the form of a dog, Mr. Fourpaws, when he comes upon two men on horseback who shoot and kill the dog's owner. The problem is that Bat is not able to get a good look at the killers to see who they are, and he hopes that Mr. Fourpaws can help him find them.

I think it's obvious pretty early on who the killers are. And the story includes the old trope of a sheriff who is under the influence of wealthy and important townsfolk, causing him to forego his lawful duties. So there are some weaknesses in this tale of the tail, IMO. However, Paula Raymond (who appeared in three Masterson episodes) plays a particularly smart and pretty lady, and that compensates for some of the plot weaknesses.

But never mind all that. I'm a sucker for dogs, and this one is loyal, smart as a whip, and adorable. He makes this episode worth the watch all by himself. I enjoyed it!
