[matese]

Hi, while I can't answer the question if a neutered male will mark if female lives in the house, I can tell you my experience with older female ruler of house accepting another female. Female #1 not spayed 3 y/o (never breed) I felt she needed a play mate while I was at work, soooo, off I went and got a baby girl, I can't # 1 was thrilled and excited over this, but, with in a few months when the baby was able to jump on and off the sofa, # 1 had no choice but to accept her new sister. #2 I also did not have spayed (stupidly on my part) also never breed her, they got along fine, now there were 2 rulers of the house. 3 years later I ran across a lil baby girl, not planning on getting another baby, but it was love at first sight, soooo, home she came with me. So now I have a 6 y/o girl, a 3 y/o girl and now baby jaws. Again the 2 older ones were not happy or thrilled over this new comer with teeth like "Jaws" so off to higher grounds both went, the sofa. Again when the baby was able to jump on and off sofa, both older girls had no choice but to accept this pain in their butt. This lil girl I had spayed, all 3 got along fine, never a growl between them, never a fight, their food bowls were lined up together, never a fight over food or stealing of food. Call me lucky IDK. All 3 were leash walked together 2 times a day, no fights. Were they perfect? Yes. I would haveto say it depends on the temperament of your dog. Pup # 1 was spoiled rotten, but as sweet as could be, pup #2 was just as spoiled and just as sweet, and the baby was the most spoiled my the older 2 and myself. That's my experience is having all females accepting new females. Also when the 2 un-spayed ones came into season their temperaments never changed, they were always sweet loving lil girls with each other. Good luck on your discussion.
