How old is your puppy? If he is really young, he cannot hold it for 6-7 hours. It is good you are going to have someone to come let him out. First off, I would lose the potty pads. You don't want him to go in the house - crate or otherwise. You want him to go outside. Personally, I think pads confuse the dog. I think your pup has too much space and too many things in the crate. He does not need food in the crate. He should eat, go outside to potty, and then go into the crate. I never left water in the crate over night, though you will probably have to do that during the day. If you have a partition, make the crate smaller. Take the bed out. A towel is fine. If he wets on it, it is easy enough to throw it in the wash and put down a clean one.
As for accidents in the house, again - get rid of the potty pads. Tether the puppy to you, so he is with you at all times. Limit his area. Do not allow him to roam. If you can gate off an area, like the kitchen, do that. Tile is easy to mop up. Don't allow this to drive you crazy. It takes time and patience. Always clean with an enzymatic cleaner to discourage him from going in the same place. If he isn't making it every hour, take him out more frequently. Take him out on his leash to a designated area. Do not make this play time. Walk him back and forth in the area you want him to go. Give him a command like "Potty", "Hurry up", whatever words work for you. When he goes - Praise, praise, praise!!!!
Never scold. Help him to be successful. He doesn't do this on purpose. He will get it. I promise. Meanwhile, check out training on the puppy forum. Do a search for housebreaking puppy. There are tons of threads on housebreaking. We have all been there. Good luck!
