Hello . I can not see the spots well enough from the small image. Can you get a larger photo?

Bloating on the right side of a frog belly is usually a sign that they need to poop. If he has not pooped for you yet, you can do a honey soak. Use lukewarm (approx 80'F) water and add about 2 drops of honey. Soak him for 15 minutes. He only has to sit in the water. Then make another bath with no honey and soak another 15 minutes to rinse of the excess honey. He should, hopefully, poop within the next day.
