Why does my dog keep peeing in the house?

This is pretty normal for puppies until they're potty trained and learn to hold it, but if your dog is potty trained and keeps going in the house anyway, there could be a number of reasons. Make sure you're taking your dog out several times a day and that the cleaner you're using to clean up the pee does not have ammonia in it. Dog's urine naturally contains ammonia, so if you use that to clean up the pee spot, it will still smell like pee to the dog and encourage him/her to continue going potty there. A cleaner with enzymes will break down the urine best to eliminate the smell. (You can also get pet-repellent sprays from pet stores, or use natural oils containing scents that dogs prefer to avoid, to keep them away from popular pee areas. These work well for some dogs, while other dogs don't seem to care.) A stressful home environment (too many dogs at a time; owners not getting along; loud, scary reprimands; separation anxiety at a sitter's house; etc.) might encourage frequent peeing out of nervousness. Or it could be to seek attention. The issue could also be medical, like a UTI (urinary tract infection) or incontinence. If the dog seems unable to hold it, is in pain when urinating, or is going super frequently, I'd talk to a vet.

There are many reasons why animals pee in the house: most commonly they are not potty trained or are "marking" their spot, however, urinary tract infections and certain endocrine diseases can also result in pets drinking too much water and having to urinate more. Especially with new dogs in the house, marking is very common- especially if either of the animals are not neutered. Neutering can help limit marking and spraying in the house. I foster animals from the shelter who are often not potty trained, and use a "belly band" on them to catch urine while I work on potty training (it only works for male dogs). If there are other signs of illness or the pet is straining or whining while urinating, I recommend taking your pup to the vet!

Your dog either isn't potty trained or just isn't going outside enough times during the day. I would recommend pad training if you cannot take your pup out enough times so that the mess is at least in only one spot. If you put the pad on the floor and the pup pees or poops somewhere else, put the pad on the pee or poop on the pad and leve it there so that the pad can absorb the scent and keep the pad on the floor (clean up the mess though!) so that the pup can smell their accidents and know where to go in the future!

It may be there your dog isn't used to its surrounding or other animals in the house. It could also be someone who lived there before had animals who marked in those areas. Try juicing lemons and spraying where the dog goes

It is normal for puppies who aren't potty trained to pee in the house. If it is a rescue dog, they may have never been house trained. If it is a trained dog, they might be marking their territory or they could have a bladder infection.
