Hi and thank you to every body who helped me with my dogs weeing problem.
My dog is marking everywhere and I have had him castrated I had it done when he was 6 months old and he his still marking I can't under stand why he his still marking can any one help:)

This may be a training issue. You have to be consistent when training and diligent.

Make sure you take him outside often to do his thing. Go with him. When he does his business outside, tons of praise. If he goes inside then take him directly outside, give the word you choose for potty then wait until he goes and again, tons of praise.

Most dogs catch on fairly quickly if the owner is consistent.

Good luck

Hi TopGirl, please try not to make too many posts about the same topic.
You could have just written this in your other topic as there were questions asked about neutering etc.

Altenweg is right though, it could just be a training issue :)
