We have a male 5 year old lab mix from a rescue, it is a good dog but needs a friend, We tried to get another male lab but when we got the new dog home it started marking everywhere. We liked the dog but we can't have our house ruined with pee and are afraid our other dog will start doing it. Can we stop it or should we look for a female dog.

Is the new dog neutered? (and is the old one neutered?) Do you know any of the new dog's history?

Is the new dog neutered? (and is the old one neutered?) Do you know any of the new dog's history?
Our first dog is neutered but the new one we tried was not neutered yet. Both dogs are rescue dogs so not much history on the new one just that someone just dropped it off in the middle of nowhere and let it.

Do you plan to get the new dog neutered?

And yes, this is fixable. We have some excellent dog experts who will talk you through the process, but none are online right now. Please be patient, and check back now and then to see if someone has tackled your question.

Yes the new dog is scheduled to get neutered on the 4th

Marking is a territorial thing, but, I wouldn't be so quick to decide that this is marking, it could be a simple matter of the new dog not being house broken, in which case this issue can be easily fixed.

How old is the new dog?

How long has it been in the shelter?

Do have the dog neutered, as this will help. It won't be an instant fix, as the hormones aren't immediately gone after surgery, but neutering is the first step.

For now, treat this dog as if it's not house broken. If it's a younger dog, take it outside at least 30 minutes after eating, or drinking. Choose a potty word, and when the dog goes, lots of praise and a treat. If he has an accident indoors and you catch him in the act, stop him mid pee or poo, take him directly outside, and then follow the above steps (potty word, praise, treat).

Remember that this dog has likely been shuffled from one place to another, and therefore probably hasn't had a lot of training, or stability. If he's spent a lot of time in a cage, which is the life of a shelter dog, then he most likely hasn't been taught that peeing and pooing inside, is not okay.

Dogs don't automatically know not to pee and poo inside. They have to be taught. Thankfully this is usually a pretty easy thing to do, since dogs love to please their people.

Time and patience, and I'm sure that this new dog will end up being a great addition to your family.

Good luck.

There are diapers for male dogs that you can purchase. It may help you with the transition for the new dog and gives you some reaction time to teach him not to potty in the house.

Seeing as how your dog has been neutered for a long time, the likeliness of your dog starting to mark is greatly decreased.

Lucky, I may be wrong, but the way I read it is that the new dog is the one marking.

I know. The op is concerned that their dog is going to start marking. He's been neutered for awhile now and I doubt he'll start marking.
