How often do pacman frogs shed?

[Bombina Bob]

Hello FF, Ive had a pacman frog (Cranwelli) since June and was wondering how often they shed when
they are around this age, it seems that mine is shedding weekly and every time i see him he seems to
be shedding. Is this a problem? I thought that it may be chytrid but right now I'm pretty worried.

1. Size of enclosure (medium sized critter keeper)
2. # of inhabitants - specifically other frogs and size differences (1 ceratophrys)
3. Humidity (not sure)
4. Temperature (83 at the highest and low 70s at night)
5. Water - type - for both misting and soaking dish (Tap water treated with Tetra Aquasafe)
6. Materials used for substrate (Cocoanut fiber)
7. Enclosure set up i.e. plants (live or artificial), wood, bark and other materials. (No plants just a water bowl and 2 inches of cocoanut fiber)
- How were things prepared prior to being put into the viv.
8. Main food source (Nightcrawlers and small-medium crickets coated with calcium powder)
9. Vitamins and calcium? (how often) (Exo terra calcium every other day)
10. Lighting (none)
11. What is being used to maintain the temperature of the enclosure (Nothing now but will use a heat pad starting soon)
12. When is the last time he/she ate (Wednesday sept 3 2014)
13. Have you found poop lately (no)
14. A pic would be helpful including frog and enclosure (any including cell phone pic is fine)
15. Describe frog's symptoms and/or recent physical changes; to include it's ventral/belly area. (Shedding, getting bigger)
16. How old is the frog (roughly 4 months old)
17. How long have you owned him/her (3 months 6 days)
18. Is the frog wild caught or captive bred (CB)
19. Frog food- how often and if it is diverse, what other feeders are used as treats (small nightcrawler and 3 small crickets every 2 days)
20. How often the frog is handled (Only when changing substrate)
21. Is the enclosure kept in a high or low traffic area (Low)
22. Describe enclosure maintenance (water changes, cleaning, etc) (Water bowl is changed every other day and tank is misted daily. Substrate is changed every 2 weeks)
