For your dog to pee in a 'new' home isn't that unusual. My male dog would be tempted to do the same but once he knows it's not allowed (or we're living in the home) it's no longer an issue. My current dog has never had an accident in the house, but when the carpet layers had to pull up new carpet (long story) they found a pee spot....left by my dog! They said it happens all the time with new carpet! I think the best you can do is buy a black light and look for old stain marks, then treat them with an enzyme cleaner such as Natures Miracle or Odormute. That will give you better results than any carpet cleaner. Accept that you may never be able to rid the house of hidden odors. If the previous dog had a problem marking the house, then there's a good chance the pad and subfloor are holding the odor. Give your dog a short course on house training, which is something any dog going into a new household should have, and watch for and treat any areas she tends to sniff more than usual. I don't think you'll have a long term problem if your dog was good about not going in the house. This post was edited by annz on Sat, Apr 13, 13 at 0:25

I found a product at the pet store called (I think) Natures Miracle" in a white bottle with red lid. It actually worked well getting puppy pee out of my carpet. I tried everything and that was the only thing that worked. It wasn't cheap and you can't even cut it with water- but give it a shot. It's a drench, easy.

If you have cats, you’re going to have issues with your floors. Whether it’s carpeting that catches every single cat hair and thrown-up hairball, wood floors that stain if your cat pees or vomits on them or any number of other problems, keeping your floors in good shape is certainly a challenge. Here are some tips on getting the best flooring for cats: Tips to keep in mind when choosing flooring if you have cats: 1. Carpets and cats don’t mix If you have carpets, you already know why I’m recommending this. I don’t know about you, but my carpets have endured just about every kind of cat mess possible. Carpet is very difficult to clean, especially if your cat urinates on it, because the urine goes through all the layers of the carpet and sometimes even into the underlayment and floorboards beneath. This makes the smell almost impossible to remove. 2. Avoid porous flooring if you have cats Hardwood floors are beautiful, and they’re very popular for that reason. The trouble with hardwoods is that they are porous, and if a cat urinates or vomits on them, it will leave a stain that’s almost impossible to remove. Add to that the fact that if there are any gaps between the floorboards, the urine or vomit will sink into the cracks and stay there until you remove the flooring. 3. Use area rugs that can be easily washed If you need carpeting for noise abatement or comfort purposes, use area rugs that you can easily toss in the washing machine. Carpet tiles are another good option because you can easily replace soiled tiles before any liquids soak through to the flooring beneath. 4. Invest in litter and food mats If you don’t want your cats tracking kitty litter all over your house, invest in some good-size litter mats — at least a foot longer and 6 inches wider than your litter box. Also use inexpensive, easy-to-wash, 3-by-5-foot throw rugs as litter mats. Put mats under your cat’s food and water dishes to avoid problems from spills there, too. 5. Flat flooring is best if you have cats Any time you can use a flooring material that doesn’t have cracks or crevices, you’ll have better results. Some of those choices include poured concrete (this must be sealed, otherwise you’ll have a porous floor that will trap odors and liquids), terrazzo and even vinyl/linoleum. And the best flooring for cats is… 1. Bamboo This is a great choice for homes with cats. It’s stain-resistant, harder than the hardest of hardwoods and completely renewable. Although it may cost a bit more up front, you’ll save money in the long run ناصر پلاستیک because bamboo is so durable. 2. Cork Another green choice, cork is antimicrobial, so it will reduce the growth of mold and other allergens. It’s sound absorbent and will help to calm the thundering noise of cats at play. Although it’s also water-resistant, you should still clean up any urine, vomit or other liquids quickly. 3. Tile Whether you go with stone, porcelain or ceramic, tile is a great choice because of its water-resistance. Some porous types of stone, such as marble, slate or travertine, should be sealed in order to avoid staining. 4. Vinyl I know — if you’re of a certain age, vinyl floors are the stuff of nightmares. But vinyl and linoleum have come a long way. You can buy vinyl flooring that looks like hardwood, for example. It’s scratch- and stain-resistant, low in allergens, easy to clean and maintain. An extra bonus: It’s quiet to walk on. 5. Laminate Laminate is popular because it looks like traditional hardwood floors. Because of the way it’s made, it may be more stain-resistant than hardwood. It also tends to be scratch-resistant, so it’s a good choice to avoid damage from kitty claws.

In his cat box. Kitty litter, Arm & Hammer brand. He has 2 cat boxes, side x side. Murraysmom has been with me through this journey. Our first pet. :0) (The first 3 days we had him he refused ALL food & water, shook like a leaf when we tried to touch him and weighed less than 7lbs. He's doubled his weight). He was 7 years old,declawed & neutered when we got him. I'm told he'd been locked in a dark garage by his prior owners. I suspect he was a little feral, when the MIL rescued him & offered him on CL. Dec 11 will be his anniversary. He's a cuddle bug...we love him & he is VERY attached to us. It was a total success story until a friend gave us some Costco cat food to try..... Here's Peeka.
