Males are commonly seen in their breeding sites after two or three days of rain, where they produce various calls in order to lure the females. Their breeding sites include low depression pools, cattle tanks, ditches, and creek beds. Males form a group where they produce calls together to attract females. As a response to the calls, the female toads reach out to the males. The call of a Sonoran green toad sounds similar to that of a buzzer and this call may last up to three seconds.

During their breeding season between July and August, they move from dry regions to wet and aquatic areas. When the female finds their mate, they go into the low vegetation area found inside water. They mate and the females lay a batch of eggs which is assumed to contain 50-200 eggs. As they breed in temporary pools and waters that tend to dry up, the eggs usually hatch within two to three days. After a period of two to three weeks, the Sonoran green toad tadpole undergoes a metamorphosis.
