In the original draft for Season 1 of Pound Puppies, Brattina was going to be Holly's sister. In the final draft, she was made into Katrina's daughter. The writers thought having them be mother and daughter would give a reason why they're both evil. Since this was a last minute change, there was no time to redesign Brattina to make her look like Katrina and her original design remained. This explains why Brattina bears no physical resemblance with Katrina.
Many fans believe that Brattina looks and sounds like Marie Kanker from Ed Edd n Eddy. Rumors have speculated that Brattina becomes the mother of the Kanker sisters when she's older. It's unknown whether or not it's true.
Brattina was voiced by Adrienne Alexander, who voiced Bright Eyes in the TV special. Alexander was the wife of Tom Ruegger, who wrote for the special and the TV series.
