Help identifying cause of death.

What was its substrate? Including the water area if you had one. I personally feel it could somehow be related to impaction, or kidney damage/bacterial infection. I don't know if this would help, as it applies to newts and salamanders, but here is an article about bloat: http://www.caudata.org/cc/articles/bloatEDK.shtml

Don't rule out the possibility of a viral infection.

Lucké's tumor of leopard frogs (kidney) is caused by a herpesvirus.....can remain latent and affect leopard frogs at the 2yr mark. It's supposedly common.
"The virus has a tropism for developing renal cells and appears to be latent until animals are over two years old. Carcinomas develop in the third or fourth summer of the frog's life."

Another common viral disease could be Ranavirus which can also cause bloating.

Many diseases cause the same symptoms....so testing and necrospsy would be needed to diagnose (swab /PCR for virus).
Diagnosis or not, fully clean and disinfect the enclosure and all materials before getting a new inhabitant.

hard to say. the most common cause is usually bacterial infection. frogs have a very fickle immune system and if they get "stressed" they can succumb to their normal bacterial flora. on the other hand, i had a southern leopard frog for a while that passed. I ended up dissecting it shortly after it died and found the bowel and stomach full of parasitic worms so it probably died from impaction.

It's not a substitute for changing the water, but a strong bubbler in there can really help keep it fresher in between.

Thanks. I'll keep all of this in mind.

Leopard frogs need a basking spot, UVB source is also important since it's active during the day and is a basking species. Although I'm not sure this could have caused the death, correct heating and lighting can play an important part in the longetivity of reptiles and amphibians
