Previously House Trained Dog Peeing in the House?

My 4 year old male, neutered Siberian Husky is peeing after being house trained. We lost his companion in 2008, and he and I suffered terribly. However, it didn't start then. Two years ago, my husband rescued a female Lab/Pit mix. We had her spayed immediately and they got along splendidly, no problems.

Last summer, my husband rescued another dog needing a forever home. This dog is a male, Mastiff/Rot mix and is approximately two years old now. The three of them get along, but then we did have a couple fights, and believe it or not, they were started by the little princess. The Siberian Husky feels like he needs to defend her, although she is nipping at the puppy (Mastiff Rot, yes he's big, but he's a puppy!). There was still no urinating in the house.

Then in December, I cleaned my carpet (not the 1st time) and the peeing began - on the carpet, the corners of my bed, all the plants in the house, and all along the wood trim throughout the house. He will even pee on my vacuum cleaner if it is setting out! As for the theory they won't pee where they sleep, well, he did! He has peed right in front of us and looks at us like "oh well." He has been to the vet and had everything checked. No problems.

Some people have said it's because I cleaned all of his scent up. Well, now the other male is following in his footsteps. You pee, I pee. I am ready to have a nervous breakdown! I put diapers on them, and they will take them off and pee on them. They all get the same amount of love and attention; they have everything a dog could possibly want and more.

Anyone have any new ideas? If so, I'm all ears. I have bought all the cleaning products on the market and invested in a new super Hoover steam cleaner. Other than this pee problem, he's an excellent dog. I can't leave them outside, because the weather has been in the 100s all summer!

My vet's wife gave me the name of someone who can, "talk to dogs". She said, I should write down a list of questions, and she will ask him and give me his answers, and this only costs $250.00.
