Não estou falando aqui dos vira-latas "puro-sangue", frutos de inúmeras gerações de cães sem raça definida. Esses sim são excelentes e resistentes pets pois a seleção natural se encarrega de filtrar as características mais importantes. O texto abaixo comenta sobre a história da evolução dos cachorros, a finalidade das diversas raças e o problema dos cães híbridos. O ponto principal é o seguinte: pra quê pagar um monte de dinheiro por um mestiço (ops, "cachorro híbrido") se você pode ter um vira-lata ou um mestiço de graça? Fonte: DogMagazine.net. Para saber mais sobre as principais características dos grupos de raças caninas, basta ler o nosso Lord Cão News sobre o assunto (em português).
Designer Dogs: Do You Know What a Pomapekeapatador Is?
With more and more ‘designer’ or hybrid dogs making the headlines featuring the likes of Puggles, Golden Doodles, Cockerpoos, Pome-Pekes and other elaborately titled canine crosses, it prompted us to wonder, exactly how did we arrive at Afghans, Airedales and Alaskan Malamutes when we started out with the animal known to most as the ‘ultimate dog’ our canine’s cousin, the wolf? What precisely is a dog breed and how on earth does one go about creating one?
People most commonly use the word breed to describe a type of dog that displays characteristics interrelated to its name. But the concept of breed is far more complex than simply applying a label to a dog which looks a certain way.
The ancestry of the dog can be traced back as far as sixty million years. A weasel like creature called the Miatis is thought to have demonstrated the first characteristics of the animal now recognised as Canis lupus familiaris, or plain-old pet dog to you and me. It is thought that this creature evolved into the early wolf.
All the canine sub-species are scavengers by nature, like the jackal and coyote and this was certainly the case for the wolf. It is though the wolf discovered easy pickings in around the waste dumps established near human settlements and as people began to see certain characteristics in the wolf which they thought would be of great help to their development as a race, attempts were made to domesticate the animal and use a selection of his most desirable character traits to man’s advantage.
Once wolves and humans became comfortable in each other’s presence, the wolf began to readily accept his subdominant role within the partnership and thus domestication as we know it, began in earnest.
Certain wolves would display particular character traits such as an instinct for guarding and those individuals who also displayed the physical characteristics to make them a force to be reckoned with would be selected for breeding in order to produce strong, confident offspring capable of protection. This is probably the earliest example of selective breeding of the dogs we know and love today.
As the selective breeding processes became more widely practised by humans, certain characteristics were developed to aid them. Dogs were bred for three main purposes, to hunt, guard and herd. As these functional breeds of dog were becoming more established, cross breeding was taking place in order to refine certain necessary attributes further.
A large dog which happened to be particularly quick over long distances may be bred with a smaller example in an attempt to develop nimble, high stamina offspring for use when hunting. Overtly aggressive canines would be bred to be as large as possible to produce effective guards for protection of the human settlements. Naturally instinctive hunters would be bred as large or as small the quarry they’d be expected to hunt. Selective breeding was in full swing.
This early form of selective breeding is how we eventually arrived at so many different breeds of dog. From the Yorkshire Terrier to the Bull Mastiff, selection by humans as well as the occasional happy accident have been the driving force behind the breeds we know and love today.
As selective breeding continued, the physical and characteristic traits of the original foundation lines were becoming more and more diluted, although every dog, even today possesses many wolf-like characteristics.
Certain types of dog breed have evolved to perform certain functions for humans. Although nowadays dogs are more commonly kept as pets, some breeds retain the original characteristics for which they were bred - although it can certainly be argued that, in the western world at least, the main function of the dog is adequately described as: to be somebody’s pal.
The hound group for example consists of two sections. There are sight hounds and scent hounds. Sight hounds are one of the oldest types of dog still endemic today. He is quiet and graceful, he is bred to spot prey from distance, hunt the prey and kill the prey. Hounds which are commonly kept as pets today include Beagles, Greyhounds and Bassett hounds.
Terriers evolved from the hound group. Terriers take their name from the Latin ‘to go to ground’, which is what they were bred to do. Terriers were originally used for hunting small quarry such as badgers, rats and rabbits. Like the hounds, Terriers should have a strong thirst for work, a thirst that if not properly quenched can occasionally lead to unruly behaviour.
The toy group is the only group to have breeds which were bred solely for the purpose of companionship. The Shih Tzu was favoured by Chinese emperors in the late nineteenth century as a companion in the palace and it was bred specifically for such purposes as were other toy group members commonly referred to as ‘lap dogs’.
The concept of what a breed actually is frequently provokes confusion today, even amongst experts. What constitutes a separate breed if two dogs look the same and were bred for the same purpose? Why are Norwich and Norfolk Terriers classed as separate breeds now when before they were the same? Why do small cosmetic differences such as ear position result in a difference in breed, when something such as major size difference does not? How can purebreds resemble cross-breeds and cross-breeds be passed off as purebreds?
All of these frequently asked questions strengthen the argument that the concept of what a breed is is commonly misinterpreted.
A dog breed is probably best described as, “a grouping of descendants categorised using criteria relevant to its behavioural and physical qualities, desirable to those who refined the line of genetic descent”. But how does one create a breed?
The offspring of a mating between two purebred dogs of different breeds is a cross-breed, a mongrel, a mutt, a dog eligible for Scrufts but not Crufts if you will. Technically speaking, the fact that both parents happen to be established, recognised pedigree breeds makes no difference to the status of the offspring.
Often described as a first-time cross, the world is seeing a huge increase in demand for ‘designer dogs’ such as the Puggle (Beagle cross Pug), the Cockerpoo (Cocker cross Poodle) and many others with equally fanciful names. The newly elected American president expressed particular interest in one of these ‘breeds’ when he added a Labradoodle to his shortlist. Although he ditched that choice and went instead for a Portuguese Water dog.
So what’s new? What traits does a Cockerpoo posses that a ‘purebred’ Cocker Spaniel or Poodle lacks?
If you or I were charged with the task of creating a dog breed, the criteria being a small to medium sized dog with a happy personality, willingness to work and learn but with a non-shedding coat suitable for people who don’t have the time to tramp 10 miles per day in order to keep this creature happy, where would we start?
We’d more than likely look at the Cocker but we’d fall short on the issue of shedding. We’d examine the qualities of the Poodle but we’d find they come in either small or large packages not small to medium and as a worker, they’d be outperformed by many of their gundog counterparts. If only the working qualities of the Cocker could be bundled with the non-shedding coat aspects of the Poodle and everything would be perfe…..wait, I’ve got it. I see a mating in the offing! Wow, how easy is this going to be. If I mate a Poodle and a Cocker I’ll get the best of both worlds - won’t I?
Erm, no. Not quite as simple as it seems.
Deliberate cross breeding is, essentially, selective breeding. There’s a problem though.
It takes several generations to “breed true.” Compare yourself to your brother, sister or even your cousins. Do you all have the same looks, the same personality, the same motivations or intelligence levels? The chances are, you won’t (até mesmo irmãos gêmeos têm personalidades diferentes). I, for example, am much clevererer and more handsomer and generally blessed with more modesty than my sibling. He, however, plays guitar far better than I play drums. We’re of the same parents (we assume) but whilst I am blessed with modesty, good looks and breath that smells like rose petals, my brother plays a mean guitar whereas I, no matter how hard I try, sound as acoustically appealing as a man shouting in to a bucket. Oh well, least I have my breath, looks and modesty and self esteem.
Each of us has some of the “best” traits of our parents. But they’re invariably coupled with the worse traits or, shall we say, less desirable traits. In some cases we may only inherit the less desirable traits of both parents at the expense of any of their best traits, our own children however may be fortunate to pick up the good traits we missed out on. And so it is with dogs.
Generation after generation of selective breeding is required before we establish a new breed. Is that a bad thing? Absolutely not.
No one could argue we should ‘stick’ with what we have in terms of pedigree dogs (BUT THEY DO) and it’s a sure fire certainty that gene pools can bottleneck to the point where new blood is required. Sorry, I should clarify that. It’s a sure fire certainty that gene pools HAVE bottlenecked to the point where new blood is required.
Should that put you off splashing the cash on a Cockerpoo, a Puggle, a Jackador or a Spoodle? Well. Maybe.
Unless you’re buying into a dog which is several generations down the line in terms of a selective breeding program, you are effectively purchasing a cross breed. Cross breeds come with many, many advantages as pets but should you be charged £600 or upwards for one?
Well no. Not in this writer’s (less than) humble opinion. You should not.
Especially when you consider how many fantastic cross and pedigree breeds are desperate for homes in Britain’s animal shelters, all of whom have the same qualities to offer. How the price of a dog is determined is a matter of some controversy and it certainly confuses me. If a ‘pedigree’ Bulldog has a going rate of £1,200 why shouldn’t any other ‘breed’ be priced according to the ‘market rate’? Another breed that, dare I say, might ‘last a bit longer’ and come with less ‘manufacturing faults’.
And here we see the start of this ethical minefield. ‘Market rate’. We’re talking about sentient, lifelong companions here - not designer handbags.
The marketing of dogs is a trend set to continue. It’s human nature to aspire to own something a little different, a little fancy or in short supply. It goes without saying, the commercialised marketing of dogs is a recipe for disaster and THIS is where the problem lies.
Watch this:
- “Oh what’s that unusual dog you have there?”
- “It’s a Pomapekeapatador” (quite obviously a Pomeranian mixed with Pekignese and a little Patterdale and Labrador thrown in)
- “Incredible, I’ve never heard of them. Where would I go about finding one?”
- “The Internet. But be warned, they’re very rare” (and therefore expensive, desirable and I’ve got one and you haven’t)
See how this works? The Pomapekepatador is what many generations refer to, rather cruelly, as a Heinz 57 (a bit of everything). A cross breed, a mix, a mongrel, a mutt. And they are as important, as clever, as giving and as worthy as any pedigree breed and there’s more than likely a rescue shelter near you chock-full of them.
Don’t be fooled, ALL dogs are designer dogs. They all have the same ancestors remember!
And if you’re really keen on modern, trendy and fashionable then you really need to consider ‘ethical’ as a lifestyle choice. So if you’re inclined toward designer, trendy, ethical dogs - you’ll struggle to do better than www.dogsblog.com - no better designer dog than those on offer (in their thousands) at rescue centres all over the UK. Just because they’re not selling for £1,000 a piece doesn’t make them any less dog - anyone who thinks differently should really come talk to me about the litter of Bengal Chihuahuas I’ve just bred. They’re SO rare, SO desirable and I’m only asking £10,000 per pup. Yes, I accept PayPal - it’s: ‘isawyoucomingyoumug@k9magazine.com’

não concordo com essa opinião purista. tenhum um cachorro híbrido.
ResponderExcluirSirius é um boxerdoodle de 2 anos a mãe é boxer tigrada e pai um poodle americano grande e branco. Meu cachorro nasceu com o padrâo de distribuição da cor na pelagem igual aos da mãe: patas, peito e ponta do rabo na cor branca e dorso preto. O focinho não é tão fino e efeminado como o do poodle e nem achatado como do boxer, o que deu a ele aparencia imponente e ele não é prognata e por isso não baba. é peludo como o poodle, ms o pelo não enrosca, não é necessário tosar todo o mes e o comportamento dele é ótimo e não foi surpresa p mim. os Pais dele tem um ótimo temperamento, são dóceis, brincalhões e sociáveis, assim como ele. Sirius herdouo senso de cuidado com os donso que o boxer tem e o amor por brinquedos e bolinhas dos poodles...
a diferença dele para as raças puras é que, levando-o ao venteriñário descobri que a chance de ele ter um cancer em decorrencia da "ascendencia boxer" e tão pqna qto a de qualquer cachorro de outra raça.
Não acho que os hibrídos são perigosos nesse sentido e nem em muitos outros. A vantagem deles em relação aos nosso bons e velhos vira-latas(dos quais orgulhosamente já tive muitos)está na facilidade com que conseguimos identificar neles as característcas das raças de que eles descendem.
Tenho uma amiga que tem um Labrakita chamado Pudim...
ele é independente como quase todas as raças orientais(akita), mas ao mesmo tempo ama sua dona mais que qualquer coisa como um labrador...
O que estou querendo dizer com isso tudo é que, não importa exatamente se esse cachorro é ou não puro, ou qto vc pagou por ele, afinal de contas, as prórpias raças puras foram junções de raças antigas... então no fim das contas...somos todos vira-latas, graças à Deus.
