Our 2 1/2 year old toy is house broken and 99% of the time comes and goes as he needs to through his doggie door and does his business and comes back in. About 6 months ago, he has started I guess marking his territory but it seems his territory has expanded from just a couple of select areas to pretty much all over the house.
He hasn't been fixed yet as we've been wanting to breed him but after having trouble finding anyone locally with the credentials for us to trust him to them, we're considering taking him to the vet to be fixed.
My question though is, is this behavior just him maturing and something that will be a thing of the past once he's fixed or is there something else going on?
There are no other dogs in the house and it seems like there are about 5 or 6 areas that he consistently goes to so that's what leads me to believe it's him marking his territory. Since we've never actually caught him in the act, I feel bad punishing him for something he did an hour ago. Is there any behavioral training I can do to try and stop this??
I've tried thoroughly cleaning the area on the wood floor with both wood floor cleaner and natures miracle to try and eliminate the odor but he still goes back to that spot. If I try to cover that particular spot with something like a towel or swinging the door over it, he'll simply wet on whatever is in his way.
It's beginning to get out of hand and we're actually about to have the carpet in the hallway by our laundry room where he seems to do most of this removed and have our wood flooring extended into this area as the carpet is practically destroyed and stained very badly.
Any help or suggestions?
