Hybrid is a cross between two purebred dogs. A purebred dog is one that has been bred over many generations to breed true, meaning each puppy that is born looks and has the same temperament and characteristics as the others. In most cases a standard is written and breeders must follow this written standard. Only dogs that make the written standard are to be bred. Purebred dogs are beneficial in that when you buy a purebred dog you know what you are getting. You know how big your puppy will grow and you know basically what type of care the dog will need. You know the dog’s limits, whether it is capable of agility, hunting, search and rescue, police work, herding, flock guarding, or just simply being a companion dog. You have a pretty good idea how much exercise the dog will require. When one breeds purebred dogs great care must be taken to ensure the lines do not become too thin. Even with all the best DNA testing available genetic problems can occur, however with the proper testing these problems can be greatly reduced.
What's the difference between a designer dog and a mutt? Generally, a mutt is of uncertain ancestry. A designer dog has documented purebred ancestry, and one knows for sure what it is. The ACHC is the leading registry for designer dogs.
Are they healthier? Hybrid dogs can still have genetic problems because you are crossing two first-generation dogs, however the percentage of hybrid dogs with genetic problems is much lower than purebred dogs because the gene pool is mixed. Breeders who breed purebred to purebred creating a first generation hybrid believe in the heterosis effect and hybrid vigor. Vigor means "physical or mental strength, energy, or force."
When you breed two different types of purebred dogs together you can get any combination of any of the characteristics found in either breed. If you are stuck on a hybrid dog how do you know which one to choose? Read the temperament and care for both breeds in the cross and be prepared for any combination of the two. If everything about both breeds matches your and your family’s personality and lifestyle, then you can most likely assume this cross will work for you.
A simple F1 generation cross is said to produce the most hybrid vigor in the dog and the further down the multi-generation chain, the more vigor is lost in the hybrid, but there are some benefits to multi-generation crossing.
Whether or not you choose a purebred dog or a hybrid , do your homework and research, research, research. Remember, purchasing a dog should be a life-long commitment and not something that should be taken lightly.
