If you mean your dog died, you get another one of another breed.
Dogs sniff each other as a greeting; sort of like you would give a handshake to say hi to someone you're on friendly terms with. This isn't harmful or wrong, so you shouldn't stop your dog from doing it; on the contrary- it means you dog is friendly! Dogs can mount each other for mainly two reasons. There's the sexual mounting, the one in which they hump, and the non-sexual mounting. The first one is to try to copulate, while the latter is done to show dominance over another dog. You can stop your dog from doing both of them like you would stop him/her from peeing in a carpet; it's all about training, discipline and being the alpha of your "pack" (remember dogs have pack mentality and, therefore, in order for them to do what you say they must consider you their "pack" 's alpha).
Another popular one is "dog dish". Less common is "dog trough".
Clean it thoroughly and perhaps put a piece of furniture over that site for awhile. Another possiblity might be to put the litter box closer to that offending site.
Buy a dog. A mean one.
you can get another dog if you have completed the broken steel add on, and have chosen the perk "puppies!" which gives you one of dog meat's "puppies." even if this dog died it will be replaced with another "puppy."

a pitbull is a dog to keep separated from another dog unless it is his female dog. An adult pibull will get along with another one if raised together and trained properly but it is not a good idea to have a pitbull with another male dog loose.
If you're talking about the one who was always peeing on the floor in the live action 101 Dalmatians then it's most likely Whizzer you're thinking about.
