Rocheal, No question is a dumb question! You are only trying to learn which I think is great!
Not all ferrets like water, but yea most of them do. I have never put my ferrets in the tub nor a pool, but my understanding is you only want the water to be a few inches deep. My ferrets like when I spray them with a spray bottle with a fine mist. As for drying them, what I do (depending on the temperature) is either let them air dry or slightly dry them with a towel then put the towel on the floor & they rub on it to dry themselves (which mind you is hysterical to watch).
What I would do it read the thread at the top of the section on ferret proofing... Get on your knees & find any & EVERY hole there is that could be a danger for your ferret & find a way to block it off. The rule of thumb is if they can squeeze their head through the hole, their body WILL fit as well! I would if at all possible keep EVERYTHING up off the flooor especially anything that is rubber or plastic. For some unknown reason ferrets are especially attracted to rubber which opposes an extreme threat to their digestive tract & can cause a blockage. Make sure the keep ferretlax or vasoline on hand at all times. I prefer the ferretlax cause it is flavored & they tend to take it more willingly. What this does is lubricates the digestive tract to keep it free from blockages & hariballs. (Yes ferrets CAN & DO get hairballs like cats). I give all 4 of my ferts about a 1" ribbon of ferretlax once a week for preventative measures.
I would leave him alone for at least a couple days before handling him too much, but yet keep an eye on him. They tend to get depressed easily. Let him adjust to the sights & sounds of the new surrounding BEFORE you introduce him to your dog. I wouldn't introduce those two for probably a couple weeks even. And when you do, watch them very closely... my mother-in-law has a pug & they tend to get rowdy sometimes cause they are so full of energy (at lease PJ did, her pug).
Albino ferrets are by no means rare. A sable is most common, and DEW's (dark eyed whites) are more common than albinos, but they are not at all rare. Do you know how old he is?
I have a few things to do today, but will try to get together a daily care type sheet for you. The websites I used to back up my information in the above post all have a TON of information in them though so in the meantime, I would encourage you to read through some of that info also as it will explain A LOT of answers.
