The only way to avoid Chytrid is to treat for it once you get the animal. The treatment is fairly easy and is the only known way currently to make sure your personal pets do not have it. It has gone viral in the wild populations and is found in almost every amphibian. I am including the instructions on how to treat it.

Terbinafine Hydrochloride Treatment


The commonly available over the counter liquid spray form of human foot fungus treatment 'Lamisil AT' (Terbinafine Hydrochloride) has been discovered to be successful in treating amphibians.[2]
Treatment is as follows:
Buy Lamisil AT Athlete's Foot Spray Pump (1% Terbinafine Hydrochloride). This is available in the USA, Canada and UK.
Put 10 squirts into 200ml of water. Soak frog for 5 minutes per day for 10 days, being sure to have solution get onto the entire frog. Keep the frog in a clean set up after each treatment as putting it back into the original tank will just keep reinfecting the frog. Sterilize and redo the original set up and any instruments that may have come in contact with the frog or its water before reintroduction of the frog. Best to wear disposable plastic gloves and swap them after frog is inserted into treatment area.

We do not use gloves when we perform this treatment. We use sanitizer and drench our hands with it then wash our hands with Dove soap and dry them thoroughly.....we do this between handling the frog and the containers through EACH step of the treatment.
