These guinea pigs come out to forage in small groups mainly early in the morning and in the evening. After that they seek cover in dense shrubs. They do not dig burrows but make an intricate maze of surface tunnels that are 8 to 12 cm (3 to 5 in) wide. Brazilian guinea pigs communicate through auditory signals and scent marks. Males are known to mark their mates and defend them from rival males.
