Carlos

Carlos was Marmaduke's only friend until he moved to the OC.

Bio
Marmaduke introduces Carlos when he got waffles from Debbie. He then announces that they are moving to the OC he was so shocked that before Marmaduke arrived he hacked a hairball. Later on, they were on the plane to the way to OC and were having on and off conversations. Carlos was faking a fight with Marmaduke at the dog park. Soon at a party at Marmaduke's house, Bosco pointed out a picture that he lied and lived with the same cat. Later on because of the house destruction, Marmaduke ran off. Maize came to the house and Carlos told her he was gone. Then the next morning, Carlos has begged his family that he has been missing but could not understand him. At the end of the movie he appears in a bark organics commercial, he briefly appears and says that's what I like about you.
