On the left foot, mine has 5 toes. But on the right foot, it only has 4 toes. It was never injured. Is this normal?

I think it's four toes per front foot. I will go home and look at mine tonight and report back tomorrow. It's not unusual for frogs to have extra toes.

I looked at my African dwarf frogs. The front feet have 4 toes. The back feet have 5 toes with little black claws on the end.

I guess the right foot never grew it's fifth toe.
