If they are agitated by each other, by their surroundings, or are stressed, then they can.
No because he is neutered
They can as they still have instinct even if they have been neutered.
have them neutered
Tell him no! then put him in another room. If he doesn't get the message, get him neutered.
There is no reason why not, just make sure that the introduction goes well be introducing the two dogs to each other in neutral territory, such as a local park.
Yes, a neutered male dog will not have as strong a scent and there won't be as much testosterone in the marking urine.
Get him neutered
Sometimes they do, sometimes they don't. I think there are two different kinds of neutering: one where the cat keeps his testicles, and one where he doesn't. The male cat that I had when I was growing up still had his testicles, even though he was neutered. That cat died, and four years ago, when I graduated college and settled into my own apartment, I got two cats from a shelter: an adult male, and a female kitten. The adult male had already been neutered by the time I got him. And he does not have his testicles. I was not involved with the neutering of either of those male cats: the one I have now was already neutered when I got him, and my parents took care of the neutering of the other one, since I was a kid. So, I know there are two different kinds of neutering procedures, but I don't know much more than that, unfortunately.
He might it really depends on how accustomed he became with the new house, and how well he reacted to it. If not well, then he is most likely at the old house.
Male rabbits who aren't neutered can't have other animal companions because they will either fight them or, in the case of unspayed female rabbits, mate with them.
Yes. To castrate is to neuter, but there may be other ways to neuter other than castration.
The Webkinz party packs with a little house on them means that the party will be hosted in a room in your Webkinz house, instead of one of the party rooms that you are brought to if you have a non-house party. For example, if you have a party from a house party pack, your friends will be brought to your house, and you will celebrate the party there. The other party packs bring you to a party room depending on which pack you picked. Hope this helps! You can post on my page if you have any questions.
Unfortunately, there is mating time and this is usually when cats will spray on everything (also inside the house if you own one and they are not spayed or neutered.) If you go to your pet store they do have a special spray out that you can spray around the perimeter of your home. Other than this, there isn't much else you can do.
