Bob is a recurring antagonist of Oggy and Cockroaches. He an angry guard dog who lives next door to Oggy. If Oggy does anything that annoys him, he beats Oggy up. He usually doesn't appear as a villain, but he is a choleric and can't control his anger.
He is a dark brown skinned bulldog with a gray belly, a large chin and a spiked leash (without a handle). He is obviously richer than Oggy, due to his gold statues in his garden and the fact he was about to buy the most expensive boxing gloves. He is also highly skilled in boxing.
He usually lives his own life and doesn't care about Oggy at all, but when Oggy or the cockroaches mistakenly end up in his garden or house, he can be very rude and aggressive, beating them up (mostly off-screen, only with fighting sounds and cat-squealing). They even destroy his property many times, much to his anger. Oggy also provokes him very often. The cockroaches sometimes team up with him to hurt Oggy together.
Bob is often just a minor character, but there are several episodes where he is the main antagonist. In these episodes, the cockroaches appear only as minor characters.
Due to the cockroaches' joke, Bob challenges Oggy to a boxing duel. Terrified Oggy has no idea how to box and begs Jack for help. They practice hard, but with no result. Meanwhile, self-confident Bob rests and watches the cats. However, when he sees Oggy beating two strong guys badly (they are actually hired by Jack), he becomes scared and practices all the night before the match. In the morning, he is tired and Oggy easily defeats him. Unfortunately, when Bob later learns the truth about Oggy's fight with two guys, he beats up both cats.
It all begins when a stork drops a noisy baby in Oggy's garden. He doesn't want it at all and dumps it in Bob's garden. As the story begins, the stork keeps dropping babies at both houses. Oggy and Bob both try different methods of dumping the babies in the opponent's garden. Oggy keeps winning, as he builds up an impregnable fort around his house. Bob then uses his money to bride the stork, causing the army of storks full up Oggy's fort with numbers of babies.
