It is okay for your dog to play with your hands as long as this does not escalate to your dog being violent, which can be prevented by training your dog when to stop. Play biting is natural for dogs, so as long as your dog isn't really biting and your hands are being injured, then it is okay.
Ok first this is a really dumb question! Second the dog just wants to play I bet
It depends on which brand of collar your dog has. Is it water resistant, or waterproof?
Mouthing hands instead of toys is a social behavior in puppies. This is how they learn appropriate social play for dogs. This can be easily trained out. When the dog tries to mouth hands, you simply take the hand away, tell it firmly, "NO!" You should then immediately offer a toy. Reward the dog for mouthing the toy and not hands.
I would not recommend it as you will be going up to other folks houses and they may have dogs too who might not like the idea of your dog being on their property. Then you may have a dog fight on your hands. Best to leave your dog at home when you go out.
Yes. The influenza virus is easily transmitted by fomites, including unwashed hands, food and water dishes, brushes and other common items. If one dog has influenza and you play with him then go play with another dog without washing your hands and changing clothes (including shoes), you could infect the second dog with influenza from the first dog.
It is perfectly OK to get a dog even if you have a small house. As long as you either have a good-sized yard for the dog to play in or you are willing to commit to going on daily walks with the dog you should be fine. If the dog does not get exercise, it will become restless and bored, and it will most likely start to destroy your furniture and anything it can get its teeth on.
your dog is like that because its thirsty or tired so let it rest ok ok.
Fur on your hands because of shedding and of the dog hasn't had a bath in a while, the grease.
That is OK as long as the dog does not have fleas.
Yes.

Not only you can play with your hands, you can play it with your feet as well.
