Dogs of Mixed Breeds
A dog with a mixed lineage of breeds is known as a mutt, or mixed breed dog. Usually, they are not the product of deliberate breeding. In shelters and rescues, you can find a wide range of mixed dogs in all sizes, colors, and shapes. Mixed breed dogs tend to be more suited to the typical dog owner’s lifestyle than purebred dogs, who are typically bred to labor, hunt, or guard. In comparison to purebred dogs, they are typically less expensive to acquire and maintain through veterinary care.
Dogs of Pure Breed
The most responsible route to obtaining a purebred dog is via a reliable, respectable breeder. Consult your veterinarian for suggestions. They will be aware of the top breeders in the area and, because they see the dogs from puppyhood to adults, they can give you great insight on health. A point to make is that the label “AKC registered” tells you nothing about the health of the animal or its parents. It is often used as a marketing ploy by the pet store or breeder. Always ask to see the mother and father of the puppy. This will give you a good indication of health and insight as to the size your new puppy will become. If you request to see the puppy’s parents and the breeder’s answer is “no,” then your answer should be no to that breeder.
It is crucial to request vaccination records, copies of the parents’ medical records, and to see the puppies’ living arrangements. Puppies mills too frequently pose as breeders.
The Discussion
The main point of contention is now: mixed-breed or purebred? I discover that most people believe purebreds to be healthier. Surely, the better the puppy, the more you pay? Not particularly on either count. Veterinarians have long believed that mixed breeds had an advantage due to their hybrid vigor. The aesthetic feature that the breeder seeks may come with some undesirable qualities. For many years, it was believed that because mixed breeds have a bigger gene pool, they would be significantly less likely to have recessive traits. But, it’s not always that cut and dried.
In June, a study done in California looked at 60,000 patient records of veterinarians and got some surprising results. According to the study, dogs of mixed breeds were equally prone to 13 prevalent hereditary conditions, including hip dysplasia, epilepsy, lymphoma, and bone cancer, as purebred dogs were. The study did find that ten illnesses, such as allergies, cataracts, bloat, low thyroid, disc problems, and liver shunts, are more common in purebreds. In mixed-breed dogs, there was only one condition that was more common: anterior cruciate ligament rupture. This study’s approach did have certain drawbacks because it neglected to examine individual breeds and instead included all purebreds into one group. It goes without saying that some diseases are more common in particular breeds than others.
What then should one think? I still tend to like mixed breeds because I believe I see more of them.
Are Dogs of Mixed Breeds Healthier Than Dogs of Pure Breeds?
Because purebred dogs may require coverage for genetic illnesses, purebred dog owners pay higher prices for pet insurance. The most recent information, however, disproves the notion that purebreds are generally less healthy and more likely to have inherited genetic illnesses.
In one study, ten genetic disorders were evaluated and examined to determine whether purebred or mixed breeds were more likely to inherit them.
Because mutts have a more diverse gene pool than purebred dogs, most mutt parents will agree that mutts are healthier than purebred dogs. However, if you pose the same question to a responsible breeder, they will inform you that a purebred is healthier due to genetic testing, inherited illness testing, and temperament testing. Thus all I have to say on this subject is based on that, as far as I can tell, no research support either assertion. In general, I believe mixed-breed dogs are tougher, healthier, and generally live longer than many purebreds I encounter in practice. Mutts, in my experience, tend to have lower incidences of inherited disease, such as some cancers, back problems and hip dysplasia.
The most startling discovery was that, for seven hereditary problems, purebred subgroups are statistically as likely to have disorders as mixed breed dogs are. The widespread belief that mixed-breed dogs are healthier than purebred canines is refuted by this. Of the ten genetic illnesses that have been studied, purebreds are more likely to have only three.
Pure Breeds of Dogs Only
Dog breeds have been divided into subgroups in order to provide a better understanding of which breeds are more likely to acquire certain illnesses.
Based on the traits of the breed and the purposes for which the dogs were bred in the first place, the American Kennel Club defines seven categories of dogs.
The following are some of that category’s well-known breeds and groupings:
• Hound (Bloodhound, Dachshund, Greyhound)
• Working (Boxer, Great Dane, Rottweiler)
• Sporting (Labrador Retriever, German Shorthaired Pointer, Cocker Spaniel)
• Terrier (Bull Terrier, Scottish Terrier, West Highland White Terrier)
• Toy (Chihuahua, Pug, Shih Tzu)
• Non-Sporting (Bulldog, Dalmatian, Poodle)
• Herding (Border Collie, German Shepherd Dog, Pembroke Welsh Corgi)
Conditions Inherited by Only a Few Subgroups of Purebred Dogs
Aortic stenosis
A constriction above the aortic heart valve or the aortic valve itself is known as aortic stenosis. In dog subgroups that include working, sporting, and herding, it is statistically more prevalent.
Dysplasia of the elbow
The most common cause of joint deterioration and deformity in large breed dogs is aberrant tissue growth. Elbow dysplasia is recognized to be prone in herding, sports, and working subgroups, particularly in Golden retrievers, Newfoundlands, German shepherds, Bernese Mountain Dogs, and Rottweilers.
Bloat: If left untreated, stomach dilatation, also known as bloat, is a dangerous condition that can be fatal. This disease affects canine non-sporting and working subgroups considerably more frequently.
Seizures
One of the most commonly documented neurological conditions in dogs is repeated brain seizures. Epilepsy cannot usually be cured. Sports, hounding, and herding breeds are more likely to experience epilepsy.
Cataracts that develop early
As the name implies, blindness results from this ailment, which appears early in a dog’s existence and clouds the internal lens. It has been discovered that purebred dogs’ non-sporting and sporting subgroups are more likely to experience this illness.
Portosystemic shunt in the liver
A portosystemic shunt is more common in the dog and toy groups. Blood is redirected around the liver instead of into it in this improper connection. To treat and rectify the shunt, surgery is frequently required.
Dilated cardiomyopathy
This hereditary disorder causes the chambers of the heart to expand and thinning of the muscle wall. It typically affects large and giant-sized dogs of the hound, sporting, and working subgroup of dogs.
Most Purebred Dogs Have Inherited Conditions with a Higher Prevalence
Allergies of the skin
Dogs that have atopy, also known as allergic dermatitis, sometimes have this ailment due to genetics or environmental factors.
Insufficient thyroid function
Thyroid hormone underproduction can have a variety of effects on a dog’s quality of life. Treatment for this illness is affordable and does not pose a threat to life.
Damage to the intervertebral disk
Neurological difficulties are brought on by IVDD, which affects the disks that separate the vertebrae in the spine. The dog’s ability to walk may be impacted by this degenerative process, which frequently calls for surgical intervention.
It is interesting to note that although the risk is increased for most subgroups of developing this condition, the terrier subgroup has reduced risk compared to mixed-breed dogs.
What Causes Health Issues in Certain Purebred Dogs?
Compared to a mixed breed dog, a purebred dog has less genetic diversity when you buy or adopt one. As long as the breeder has taken the necessary precautions to ensure that the puppies she sells are free of genetic illnesses, this could not be a bad thing.
In an ideal world, every purebred puppy purchased on this earth would have received proper socialization and care prior to adoption, as well as a genetic illness certificate. Nevertheless, the truth is that responsible puppy sales from purebred parents cost significantly more than puppies from backyard breeders or pet stores, and disease testing and appropriate socialization need time and resources selling puppies sourced from an unethical puppy mill.
I have witnessed numerous tragic scenarios in which a person brings in their purebred puppy for the first time for a checkup, only to discover that the puppy has one or more genetic disorders that the breeder or pet store failed to detect or even test for.
