Wally brings home a pregnant Great Dane that was partial payment from a client, but his daughter is allergic, so he tries to give the dog away to Beaver. June puts the kabosh on that idea, but playing with the dog puts the idea of getting a pet into the heads of Beaver's sons, Kip and Oliver. They end up - without Beaver's knowledge - adopting a pet tarantula. This plan goes south when the tarantula ends up on Mary Ellen's shoulders. As a result, Beaver tells the boys that they can never have a pet, giving the death penalty to their dreams in that direction.
Meanwhile, Oliver has discovered an elephant at Miller's pond. He, Kip, and Kelly decide to hide him in their grandma June's garage and take care of him since they don't want him returned to a circus. This requires massive amounts of greens and peanut butter. How does this work out? Watch and find out.
This episode continues the tradition of the original LITB it promoting responsibility in conjunction with pet ownership and also getting a pet that fits the household needs. Apparently, even Wally at middle age is having trouble learning that latter lesson.
