Chubby Frogs as pets Chubby Frogs are now commonly sold in pet stores. Those considering chubby frog ownership should be aware that like most amphibians, Chubby Frogs cannot tolerate the chlorine found in standard city water. Pets must therefore be provided with treated or spring water. Also, frog owners need to consider that Chubby Frogs can be fairly uninteresting as it is quite an inanimate frog.
