Why can’t a dog have a male and a female

Why you can’t have a male and a female dog It is possible to have a male and a female dog, but the breeder needs to spend more time and effort. A male and a female dog will also fight, the dog has a strong sense of territory, both male and female will defend their territory. And raising a dog for a male and a female, into the estrus period is more problematic, will always mate to have pups. If the breeder does not intend to have pups, the two dogs need to be taken to the hospital as soon as possible to spay and neuter. Breeders need to treat both dogs equally when raising them. Do not be too close to one of the dogs and leave the other dog out, this can easily cause fighting between the dogs.
