They can breathe with lungs and can perform oxygen exchange through their skin when moist. Well I theorize that when they hibernate, they go underwater into the mud at the bottom of ponds. Now how is a frog to breathe underwater? while underwater their oxygen requirements are low, but they still need it. That is why they can also perform oxygen exchange through their skin. probably because they're amphibians.
Frogs are amphibians. They can breathe using their lungs* on land, or absorb oxygen through their skins when underwater (this is called cutaneous respiration). Lacking diaphragm muscles, frogs on land may be said to "swallow" air : they inhale air through their nostrils, inflating skin sacs in their throats, then press down with the mouth muscles to force it into the lungs.
Frogs have no proper nose. However, they do have nostrils which are an accessory structure for respiration since frog rely on buccal pumping (breathing with the cheeks) for respiration.
A frog is an amphibian, but adult frogs do not have gills. They absorb oxygen from the water through their skins, using special blood vessels. If the oxygen level in water is too low, frogs will move around to increase the water flow across the skin. Some frogs have creased skins that can increase their surface area. (see related question)
Frogs have underdeveloped lungs, so they must have a moist skin so that oxygen can diffuse into their bodies. Their lungs do not function well enough to be used on their own.
The frogs have mucus glands in their skin that secrete mucus. These mucus glands keep the frog's skin moist so that the diffusion of gases can occur. Oxygen diffuses into the frog's bloodstream and carbon dioxide diffuses out.
fish breathe through their gills. frogs breathe through their legs while in water.

Through their skin. If kept moist frogs do quite well in this mode of respiration.

The class of chordates that have a dual life are amphibians. This group includes frogs, toads, newts, and salamanders,
frogs use their skin for their respiration (since it is filled with capillaries). For most amphibians, 90% of their respiration is done through their skin. Frogs can also breath through the lining in their mouth which also contains capillaries, so a large amount of gas exchange can take place there. Frogs are able to breath through a pair of lungs as well, though this is used as more of a back up.
a special type of respiration, mostly take place in frogs and other members of of reptiles ,through the buccul cavity
Lungs and moist skin.
