Hi there, my girlfriend while away left her tortoise in the care of her parents. She is now back and believes her Hermann's tortoise to be showing signs of dehydration. Eyes are a little sunken, one of which appears very irritable to him and he is also noticeably lethargic. He is eating, but today she went and bought some Dioralyte to bathe him with a couple of times a day to get his hydration back up. Just wondering what the ratio is? They come in sachets and are directed to mix with 200ml of water. Is this the same when bathing her tortoise? Thanks
