67Camaro: You may need to increase your watering setup to keep him hydrated better on a daily basis. Either mist his cage more frequently, or add a dripping system for him to obtain more water (if you don't already have one). Since he is a year old, he may definitely take a shower (showering is not recommended for babies - only older chameleons). I will copy and paste the shower system I use for my chameleons from previous posts here on this forum. It works quite well for dehydration and my chameleons love it. Give it a try and see if his problems are relieved. If after giving him a shower, he still exhibits difficulties, it might be a good idea to consult your veterinarian.
Showering: I have a little tree in my shower (a silk tree so as to not cause overwatering a live plant) which I use to give all my chameleons soft, warm showers... Make sure the water is not hot or not too cold and not on full blast (this can hurt their eyes). Run the water softly as if soft raindrops were floating down, put your little tree under the "pretend" soft warm tropical rain and let your chameleon have a very enjoyable shower. If very dehydrated, he may stay in the shower for 30 mins or more drinking. You may see him stretch his head and neck up as he drinks... this is normal. Let him drink as long as he wants... when he starts to get restless or stops drinking, then remove him from his shower. Make sure you place him under his basking light afterwards so as to not get chilled.
By the way, you may use a live plant if no silk plant is available to you. It just might cause overwatering a plant if used in showering methods frequently and can cause a bit of a mess on the shower floor from dirt, etc. I'll put some images of Cyro, one of my Ambilobe panthers, taking a shower below:
Hope this helps, and like I said earlier, if this doesn't improve his difficulties, a trip to the vet may be in order.
Good luck!
