Can you breed any two dogs? Essential Tips

Increase genetic diversity for a canine study

Scientific and professional studies will often contact well-renowned breeders and ask for the data of all their breeding dogs and litters. This increases the studies’ sample size, increasing the validity of the results. It can also benefit breeders. Their details can be included at the end of a study for others to view, thereby reaching a big audience.

A high-quality study has results from many different individuals to minimize bias. By breeding random dogs together, their puppies’ physical and behavioral characteristics can potentially all be different in a litter. This will more accurately represent nearer all of the different dog types that exist. As opposed to one breed type being used which will induce bias through similar characteristics.

For example, in a study concerning dog temperaments towards vacuum cleaners, if you were only to use a breed such as the Labrador Retriever, the results may be more positive. Generally, this breed is more docile so it will not accurately represent the species.

Fewer Congenital Issues in Some Cases

Its true that many purebred dogs suffer from genetic conditions that have been passed from one generation to the next. Careful cross breeding may lower the chances of passing on a particular condition if only one parent is a carrier. Theres an often-repeated belief that mixed breed dogs have “hybrid vigor” and are healthier than purebred dogs. In truth, its difficult to say one way or another if purebred versus mixed breed life expectancy differs significantly. Purebred dogs are more likely to suffer from genetically inherited conditions, but this does not mean that mixed breed dogs live longer as they can pass away from many other types of disorders.

Could my dog be pregnant by two dogs?

Two factors conspire to give the female the greatest chance of falling pregnant. These are:

  • Sperm can remain viable in the female reproductive tract for around 7 days
  • The female doesnt have to ovulate on the day she is mated to fall pregnant
  • Long story short, theres a lot of flexibility in the timing of fertilization. This gives scope for two (or more) lots of sperm to lurk in the female reproductive tract to fertilize an egg.

    To understand this better lets look at a female dogs estrus, or heat, cycle.

  • She comes into estrus or heat twice a year
  • Each season lasts approximately 3 – 4 weeks
    • The first 7 – 10 days the females vulva enlarges, she bleeds, but she wont stand for a dog
    • The middle 5 – 10 days the female ovulates. This is when she will stand to be mated and may fall pregnant
    • The last 7 – 14 days she slowly comes out of heat
  • Ovulation can occur at any time during that middle period
  • Unfertilized eggs can survive for around 48 hours
  • If two male dogs mate with the female on the same day, its a straight swimming race between the sperm as to which reaches the ovum first and fertilizes it.

    If different males mate with the female on different days, she can fall pregnant by both of them. This is because the sperm survive for days in her tract, and are ready and waiting when she does ovulate.

    PEOPLE BREED TWO DIFFERENT MALE DOGS TO ONE FEMALE IS THAT POSSIBLE. MASTEROFALLBULLDOGS SAID YES

    You dont have to choose between your pet and your wallet when it comes to expensive vet visits. Prepare ahead of time for unexpected vet bills by finding the pawfect pet insurance.

    A female dog comes into heat twice a year. If you are planning on a litter of puppies, then timing is everything, especially if the female is to mate with a stud dog. However, Mother Nature may have other ideas. Her priority is to perpetuate canine kind and shes not fussy about who fathers the litter.

    Imagine then, the scenario where a purebred female from a rare breed escapes while in heat. Those jangling hormones are going to send her looking for a mate… but it might not be the breed you had in mind. What are the implications for any subsequent purebred mating and any puppies born?
