Indoor Dog Invisible Fence?

I have seen them at Petsmart the other day and while I don't have any experience with them and don't remember exactly what they cost, but I do remember thinking that it wasn't too bad.
A friend of mine just got a wireless invisible fence for outside and it works great for her dog. You do have to remember that you have to train the dog for the e-fence though and that will take a while (though your labradoodle may get it quickly).

Personally, we have opted for a cheaper solution to keep our dog confined and have gated off the kitchen with a large baby gate. Our dog doesn't cause any problems per se, but I don't want her on the furniture or chewing up toys my DD may have left laying around - so when we are not supervising her she is confined to the kitchen where she also has her bed and any messes she may make are easy to clean up.
I don't find anything wrong with keeping her restricted to one room when we are not there and when we are around she is with us in the rest of the home (minus the bedrooms).

The one other thing may be medication. If it is an anxiety/insecurity issue some anti-anxiety meds might help.
Good luck.

Just a thought, but if your vet said he is insecure and that is the reason for the marking, did you ask the vet how to make him feel more secure?

Seriously. Dogs are not people and the same behaviors (comfort measures, typically) that people would use to make a person feel secure, do NOT make a dog feel secure. They need someone to be in charge in order to feel secure. The fact that the dog is marking sounds like he feels like HE is in charge. He shouldn't be. YOU should.

Did you discuss any of that angle of it with the vet? Do some reading on dog behavior and see if you can figure out a different approach to daily life than what you are doing. It may help. With dogs it is always the little things. Who goes out the door first, for example, speaks volumes to a dog. To us. we are being nice or whatever... it is more "practical"... however you want to look at it. To them, it is a deferential act that means that THEY are the alpha of your pack.

I suggest a new trainer that works with you guys at home.

We have an electric fence inside and out. We bought ours at Home Depot. That was the cheapest we found. The collar is the expensive part. When ours have stopped working I think my husband has bough them off of eBay. Maybe they are cheaper there? Not sure.

Ours works great. I love having the dogs in the areas I want them and out of the areas I don't. And honestly our fence hasn't been working for weeks but the dogs don't even try to go past it. When they were younger they knew within a few hours if a battery was out and they could cross the line. I think they have gotten old and lazy.

We don't want our dog upstairs because my mom is very allergic so we keep the upstairs dog free for her when she visits. We installed an invisible fence under the floor in the two pathways to the steps and it worked great. If the basement isn't finished it was just a matter of putting the wire in the ceiling in the basement. If it is finished you would need to put it up where the rafters are. We used the Invisible Fence company but I think now you can buy the cheaper version at Home Depot and do it yourself. There is also training even when using the fence but probably quicker than when not using one.

I didn't read all your responses but I have a friend who built a new house and didn't want the dog getting into the new drapes. They ended up burying the invisible fence in the ground under the windows that they didn't want the dog near. It worked great for them. They had a company do it too but I can't remember which one.

Look into a behaviorist. Our own vet has hired one to help with some dog issues she is having with her rescue.

Does he only mark when you're not home? If so, try crate training him.

I have the Invisible Fence brand both inside and outside. It works wonderfully for our purposes, but I don't know about marking. Sounds like you might need to work more with a behaviorist or trainer to get to the root of the insecurities. Anyhow, I have a mischievous Poodle who was getting into our garbage and getting into trouble in the mudroom where I store the dog food and treats. I also didn't want any dogs in the more "formal" (in quotes because it's for practicing piano and playing with Legos right now) living room and dining room. We have three indoor units set up that keep both of our dogs out of the two formal rooms, away from the kitchen garbage and dishwasher and out of the mudroom. We used a professional trainer to assist in the training. My poodle is persistent and took several rounds of training and needs his electronic collar turned up to a fairly high level. The Shih Tzu took to it immediately and requires only a beep (no shock) setting on his collar. The trainer was very useful in determining the setting levels needed for both inside and out and then setting them for us. Each dog's setting is individualized for both in and out. I was a little apprehensive at first, but now I love it. I do wonder about marking though--if you keep him out of one area, will he just find another area to mark? Good luck.

I'd start with a professional trainer who will come into your home and work with you and your dog. I'm certain a good one can train YOU to train your dog.

If it were me, I'd put the training collar on and watch him in the house. Everytime he stopped at a place he liked to mark, I'd tell him to "leave it!" If he left the spot, I'd praise and treat him. If he still lifted a leg, I'd give a correction with the collar. Repeat several times. Praise/treat when he leaves it, correct when he lifts the leg (or sidles up to something like he's about to lift the leg).

Then I'd take him outside. I'd walk him and allow him to mark around outside, each time praising him and treating his behavior so he knows that he can mark outdoors on trees and such, but not indoors on your stuff.

Do that each day for a full training session's length (based upon the attention span of your dog). I don't think that you need an invisible fence, just time and focused training.

Is he neutered already? Have you tried belly bands?
