Will a new male dog pee inside my house to mark his territory?

This is likely a behavioral issue that will be a hard habit to break. He is probably being territorial, and being intact will increase his behaviors. You can try neutering him, removing the female, or confining him when he cannot be monitored.

It is possible, but it is also possible he is urine marking because if he was only neutered in the last few months, or merely because there is a new cat present. I would suggest the following article to help; https://www.petcoach.co/article/6-common-reasons-for-potty-accidents-in-dogs/

This can be a frustrating problem in intact males! The first thing I would do right away is have Junior neutered - many times, this will decrease the marking behavior dramatically even if it's already been going on for several years. After this is done, you will likely still need to work with him a bit on housetraining. Treat him like a young puppy who has no idea where to potty - take him out frequently, praise and reward for peeing outside, and supervise constantly indoors to prevent accidents. If you see him starting to lift his leg, clap your hands and say "ah-ah!" or "no!" - he will soon learn that this is not acceptable in the house, if you are consistent. Don't relax your supervision until he has had at least two weeks with no accidents at all, then increase his freedom in the house very slowly. This will take time and patience, but it can definitely be done.

If this behaviour is related to territorial attitude (as normally is) and so related sexual hormones, yes it will. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

He probably started marking when his hormones increased. Now that he’s neutered these levels will go down over the next four to six weeks. Please clean all of the area he’s marked with lemon or vinegar cleaner to remove the scent. I recommend going back to crate training for housebreaking, or using a male belly band when you aren’t able to monitor him. Please take him outside or to the pee pad frequently so he has a chance to urinate there. Marking behavior can become a habit so working to stop this right away is best.

Inappropriate urination occurs when a dog regresses to urinating inside the house. This behavior is more common in male dogs that have not been neutered, although it can occur in non-neutered dogs and cats. The first thing to rule out is inappropriate urination that occurs when there is an underlying health problem which is causing a dog to urinate inside the house. It may have lost control of the muscles in its bladder or sphincter, or there may be an infection (UTI) or other condition as drinking too much (seen in many medical conditions) that is making it difficult for the dog to hold it in long enough to get outside. When a medical caused has been ruled out we can think about the second type of inappropriate urination which is behavioral (such as marking). I recommend to take Bakar to the vet with a "fresh" urine sample to first check or rule out medical causes. Hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach.

The short answer is: maybe. Urine marking can develop into a set habit of behavior, and it can be difficult to get them to stop completely if they weren't neutered at an early age. However, in trying to minimize the behavior, the very first thing you should do IS to neuter your dog, so you're already on the right track. Here are a couple of great articles that you may find helpful in terms of curbing this behavior. https://www.spca.org/document.doc?id=116 https://www.petcoach.co/article/7-rules-for-effective-housetraining/ I hope that helps you!
