Do dogs "mark" brand new carpeting if they ruined the old stuff?

Yes, dogs mark thier spots. New carpeting will make no difference. To a dog, its new territory and marking their spot is normal.

Wrap a Depends on their rearend.

The male is probably marking his territory-is he fixed? I’m not sure females do this…

Yes, an intact male will mark his territory if there’s a female around. Especially if she’s not been fixed. I’m thinking the smell of an un-neutered female’s urine gets him going faster.

Dogs pee on places where other dogs have left pee. If you put down a moisture barrier before you lay down new carpet that would mitigate the smell working its way through to the carpet. Depending on the pile of the carpet, a bichon may not be large enough to produce enough urine to work its way through the back of the pad. Moisture barriers are not always the best Here’s a link:

(The information you want is at the bottom of the page. Oh, and if you decide on the moisture barrier, have them seal the seams on the carpet pad.)

Both dogs were fixed following the birth of their five puppies. So now I can’t get new carpet.

I wouldn’t say “Don’t get new carpet.” If you have to alter your life to the point that you can’t even enjoy your own home because of your dogs’ behavior, it may be time to either get rid of the dogs (not an option for many people who love their animals). Or if you have the money to get new carpet, perhaps you have the money to consult a dog trainer/animal psychologist, and don’t give up. Let us know how it goes too!

I got this question, but to be honest my one dog never peed anywhere but outside, my other dog would pee at the door when she was a pup but now has also not peed indoors ever since her puppy stage. I was told the reason they pee in the house is because they aren’t getting the general idea of where they actually should be peeing. Once they get older it just becomes a very bad habit…you should let them outside to pee A LOT and try to break the habit before letting them in on the carpet.
How do I stop my dog from peeing in the house FAQ

Good luck! :)

My daughter had a spray that makes animals not want to pee where you spray it.

I had a friend with a dog that peed and pooed everywhere. I gave her a doggie diaper, and told her to put a sanitary pad in there to soak up the pee. I told her to make sure the dog wore it the ENTIRE time the dog was in the house. So that meant that she had to take the diaper off outside, and put it on again outside before the dog came back in. It does not work with every dog, but this dog would NOT pee in the diaper. The dog was house broken in a very short period of time.

I’m sorry; I forgot to say this misbehavior was when we first moved in , early last year. They’ve stopped doing it and have a doggie door/locked fence. So I was thinking if they’ve truly stopped if they’d start up again because of the new smell of carpeting? And no; we could never give them away just because they’ve ruined carpet in one room and the hallway. Well; maybe two rooms.
They go outside dozens of times a day.

I’m guessing you have your problem resolved. When you have the old carpet taken out, inspect the floor underneath. Clean and deodorize it if necessary, (maybe a coat of Kilz will do the job), and move on. Sounds like the dogs already have.
