I think it just depends on the dog if he will stop marking after nuetering. Sunnie is 4 1/2 yrs old and was nuetered about 6 months ago. He used to mark a LOT!. Now he has completely stopped. Beamer was nuetered before he learned to mark. Infact, he will be a year old in a little over a week and he never has lifted his leg. He is still a squatter. lol |
