Male dogs are notorious for this and will think nothing of lifting their leg to the side of your couch or chair. The best thing to do is keep your dog in the kitchen or another room (even outside in the back yard if it's fenced, then let it back in either in your basement or laundry room) until you can see your vet and find out what a good spray is that you can spray on the areas your dog has peed on. Dogs will always go back to the very spot where they have peed and also if you've had a dog before this one they males can sniff a gnat's pee at 100 paces away. LOL Get that spray .. it works! Good luck Marcy Get the dog neutered. Period. It will help immensely with behavior issues such as this, and it will make him a happier pet who's less likely to become aggressive or run away. Contrary to popular belief, it will NOT make your dog fat, lethargic or wimpy. Also, you will have to thoroughly clean everywhere he has peed or he will keep hitting the same areas over again. Get a UV lamp - some companies such as KV Vet Supply sell these as Urine Detectors but I think any UV light will do.
he's marking his territory
Your Dog is just telling your sons dog that it is his house and is marking his teritory
If the dog is marking for sexual reasons, then it is possible that castration will stop him doing this. Unfortunately, many dogs initially mark for sexual (/territorial) reasons, but after a while the behaviour becomes learnt. Castration will stop innappropriate sexual behviour, but may not prevent urine marking (which may have become a learnt behaviour). Get advice from a professional behaviourist if castration doesn't help.
You can get the male dog neutered, this should stop him from urinating in the house as much as he did.
Maybe they feel like that is marking their territory inside the house?
He will eventually, my dog is six and he was neutered. Give it a couple of weeks.
Keep your dog inside the house
In case it is male: marking its teritory
If you have another dog he will try to mark his or her before the other, it you house is dusty it smells like outside dirt and they smell it and they mark as close as they can by were they smell it
your dog is probably marking his/her territory since it is an unusual place. keep reminding your dog that it is not right to go on the floor.. Thanks!!!
If "he" is indeed a male he's probably "marking" territory. Have him neutered by a vet.
* Spay or neuter your dog as soon as your vet recommends. * Take care of fights or dominance issues between your dogs. * Limit your dog's ability to see outside animals from inside your house. * When urine-marking occurs, clean the area immediately. * In areas where your dog has urinated try to keep him from it or take away the attraction. * Keep things that could encourage your dog to mark out of reach. * If your pet is urine-marking in reaction to an addition to your household (i.e., a new roommate, boy/girlfriend, spouse etc.), have that person and your dog get to know each other. * Learn the signs that indicate your dog is about to urinate and watch for them when he is inside. * Use the "nothing in life is free" behavior with your dog.
