Since we acquired the Pekingese, my Rottie has started urinating in the house. I know he's doing this to mark his territory e.t.c but I can't seem to stop him doing it. When he was a pup, it took us a week to house train him. Unfortunately, when we're not watching him now he's taking a leak on the bedroom door, the puppy's crate or anywhere else the little guy has been. He doesn't do it when we're there because we've previously corrected him for doing so.

My wife reckons we should leave the Rottie outside from now on, but I disagree since:

a. That's avoiding the problem - not addressing it

b. The Rottie was here first so I don't see why he should have to suffer. Plus, it might end up making him resent the other dog too. God knows what would happen then.

Anybody have any advice?

The simplest advice, and sometimes hardest to do, is not let him out of your sight. Treat him like a not yet house broken puppy. If you can't watch him, then crate him or put him out.

Andy : just marking the place that is his now that you have brought another dog into the house ,treat him as a new dog and if you are not able to watch both dogs ,then crate them till its time to take outside and re train bathroom times .Good luck Peter

What I sometimes do with a new puppy in the house is to tie their leash around my waist. It's hard to forget them that way.

Sounds like a dominance issue to me. Or simply a young dog who thinks now is the time to start trying to take over. The dog is in a crate. When he is not in the crate the leash is attached to him. Not neccisarily to you just him. This is where you as a human must concentrate and watch him. Correct him before he goes. You should know when he is about to 'mark' if you know your dog. Get him BEFORE not during and certainly not after.

I've seen some dogs get alone well, being brought up together things work out. But when you bring other dogs like this in, you have to keep a eye on things. I would definitely crate the Pekinese until he learns how to act and when I bring it out I'd place it on lease or have it drag the leash around. This is to get him use to wearing a leash and to discipling it when it acts up.

Just because its little and looks like a mop, its still a dog. So the same rules apply. Personally I don't like little Lap dogs, or tiny yapping dogs. But I still see no reason for the little guy to die. I mention this because if the puppy happens to bite and hurt the Rott or pick up one of the Rotties toy and you are not around there is a chance that neither will the Pekinese, after this. Dogs that are brought up with each other can play ok, but if they are brought in and ones already has established territory and both not taught to socialize, it is survival of the fittest. My moneys on the Rottie. You got to setup rules and regulations, what will be accepted and will not. Get that little guy in check, it doesn't matter if you think he is too little to be a threat, its how the larger dog views this intrusion. <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />

I'm combining comments for the previous post where you introduce the mini bitbull on steroids, and your fear that he may get hurt.

The Rottie is marking his territory, first comes the rain then the fire, crate the Pekinese before he gets crushed. Even a well socialized dog will start laying out ground rules in his house if he starts feeling threaten or that he has to share what was once all his. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

Crate the Peke??? Why what is he doing thats wrong? He is not the one marking his territory. The rottie is not the end all be all. At least shouldn't be. It should be the human. Teach the Rottie who the boss is. The boss has introduced a new member to the pack. It is not for the rottie to say no. What would you do if you brought home a new baby? It is a new member to the pack. The rottie needs training.

The Rottie's not saying no....he's saying "I'm more rank than the Peke".
This is a pack issue....the Rott is establishing and showing his rank to this new member.
You should kennel/crate one or both. I dont know what luck u will have with this one.
The good news is the Rott did'nt eat him......yet! <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />

Tod in his previous post, he said that the little dog, was showing signs of aggression. I agree that the Rottie should not be allowed to pee in the house at will. But he didn't have a problem until the little dog, came into the picture. I'm thinking if he gains control of the Pekenese the marking may stop.

If it does not stop, the Rottie needs to be either crated or placed in a kennel outside and brought in when the family is in the house. So that he can be watched and corrected if necessary but the Pekeneses is acting like a bit bull on steroids (in his previous post), I'm assuming barking and acting aggressive, (because he is afraid, probably) so that is why I said crate him a gradually introduce them. Correct the dog who has the problem. If the Rottie continues his marking problem after the Pekenese has been crated, then put him outside. <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />
