|This article is about the Casagrande family dog. For the ninth Loud child, see Lola Loud. For his namesake, see Lalo Alcaraz.|
When Lalo was a puppy, Hector wanted to buy a dog for his family. He decided to buy a puppy from a lady in the park. At first, he encountered an unnamed vicious dog, which he described as malo. The lady selling the puppies agreed with him that "Malo" was the perfect name for the dog because he had a terrible behavior. Hector then discovered the puppy's brother, who was the exact opposite of him, so he decided to adopt the dog and name him Lalo.
Lalo is a friendly, and joyful dog, as demonstrated by the fact that he welcomes all guests by charging onto them and licking them, and will also lick his owners. He likes to play, and often joins in with the Casagrande brothers and Sergio in their games. Lalo is very loyal to his owners, and will go along with most of their plans.
On the rare occasion that Lalo does show aggression, it's usually due to fear or distrust. This is shown in "This Bird Has Flown" when Lalo tries to attack a drone masquerading as Sergio and in "What's Love Gato Do With It?" when he attacks Bobby, who thinks he is a cat because Lalo is afraid of cats.
He also likes eating a lot and will eat most human food in addition to dog food, unless it's too salty as seen in "Cursed!".
He is a Bull Mastiff, with yellow fur, brown ears, a light brown muzzle, a black nose, and black spots over his eyes. He also wears a black collar, with a white tag, he is also very large.
