Breeding Pets in The Sims 2 There are a few prerequisites for breeding pets in The Sims 2: You must have a pet house.You must have a good relationship with the pet.The pets must have a good relationship with each other (more than 25 points daily). When pets are ready to breed, they'll go into the pet house. When the female animal gets pregnant, you'll hear the same sound that plays when a Sim conceives. She'll be pregnant for three days before delivering, just like with Sims. The Sim's pet may give birth to up to four puppies or kittens.

The amount of money you earn depends on how well the pet has been trained. Large and Small Dog Breeding in The Sims 2 While it's possible to breed a small dog and a large dog, animals can be only as large as their mothers, so a small female dog will always give birth to small puppies. You'll generally have better luck breeding pets of the same size. If you want a big dog, make sure both of the parents are large. What to Do When Your Pets Won't Breed If your pets are having trouble with their relationship, try keeping them in an empty room together to force them to play with each other. If there aren't any toys, and just some food, litter boxes, and beds, it'll be easier for them to breed.

Likewise, you can have a lot with six Sims and four pets or eight Sims and two pets. Ideally, you want to keep pairs of animals of the opposite gender so that you can breed them.
