My Dumb Dog

The Labrador is without a doubt a very beautiful creature that is also well built and sports a sturdy frame that is almost like that of an athletic animal. The breed comes in a number of skin colors including Black, Golden and Chocolate and in addition, the coat is generally thick and short and the hair is extremely straight. In fact, a Labrador Retriever has a double layered as well as dense coat. The Lab has a very intelligent bent of mind and at the same time he is docile with the elderly as well as with young children.

However, as with any other breed there are certain Labrador problems that every owner will have to look out for including those related to their health as well as their behavior. Nevertheless, the Labrador is generally a healthy animal though it can suffer from hip as well as elbow dysplasia and cataract as well as epilepsy. What’s more, if you fail to give proper Labrador training, or if you let your pet become bored, it could lead to some behavioral problems that can only be prevented by expending some extra effort, and providing better care and proper training.
There are certain Labradors that can prove to be a handful and these pets will not easily learn to behave properly unless sent to a behaviorist. This and other Labrador problems such as having a pet that always seems to be dreaming can be reason for you to become worried, though in reality these can be overcome through proper Labrador training. A typical Labrador problem that many pet owners will have to deal with has to do with a pet that chews up everything he can sink his teeth into. Such a problem can arise when the Labrador is too energetic and it also occurs when having someone or something invade his territory frustrates the Labrador.

To overcome these Labrador problems, it would pay to talk to a veterinary behaviorist or provide strict Labrador training and also ensuring that you spend a lot of time with your dog in helping him release his energy in a more productive manner.
Typical of Labrador problems is that of chasing cats and since this is more of an instinctive driven behavioral problem it can best be changed through giving your pet proper Labrador training which may require spending a lot of time and being patient so that he is taught how to stop this instinctive reaction on his part. Another common behavioral problem that your Labrador can show is that of becoming destructive and this in turn is generally due to his becoming anxious about something. Because dogs have advanced hearing capabilities, they can become aware of things even before humans get wind of these things and thus your Labrador may behave in a manner that is incomprehensible to human beings and so, this is another common Labrador problem that pet owners will have to contend with.

It is also always possible to condition your Labrador to not become skittish when he hears various kinds of sounds and a simple Labrador training step you can use is to play recordings of certain sounds at low volumes and then increasing the volume gradually to make your Labrador get accustomed to these sounds. In fact, this is an especially useful way to becalm your Labrador who could otherwise become so nervous that you may even be forced into giving him anti-anxiety medicines to overcome his fears.

Most Labradors are well behaved and enjoy good health, though if you notice Labrador problems in your pet such as chasing cats, daydreaming or chewing up things, you need to start Labrador training. To find information about expected Labrador problems, you can read dog training books that highlights a few common behavioral problems noticed in the Labrador retriever.

Various contentions have been put forward in the dog world by some, (eg those against mixed breeds), that ‘hybrid vigor’ is allegedly not possible (for example) when breeding labadoodles (ie mixed breeding of Labradors and Poodles) as it is alleged that hybrid vigor is only possible with mixed breeding of unrelated animals (eg horse and donkey). However, that it not correct.

For example, see http://www.ermanz.govt.nz/resources/publications/pdfs/ER-IS-03-01.pdf:

“What is a hybrid?

A hybrid is an organism resulting from a cross between genetically different parents. Hybrids can arise from crosses between closely related species (interspecific hybrids) or by crosses between different types (subspecies, varieties, cultivars) within a species (intraspecific hybrids).

Hybridisation occurs naturally, but it is also widely used in selective breeding programmes for both plants and animals. The mule is an interspecific hybrid between the horse and the donkey, bred to combine some of the favourable characteristics of each parent. Intraspecific hybrids often show ‘hybrid vigour’ (heterosis), growing more vigorously and yielding more than in-bredlines.”

Hence, labrodoodles are ‘intraspecific hybrids’ (ie are within species breeding) and do show hybrid vigor.

Also, see http://www.country-wide.co.nz/article/449.html:

Another important but often forgotten principle is what happens when you interbreed the first cross (F1) progeny. In essence if you breed (F1) sires and dams together, there will be less hybrid vigour in the progeny. Like wise hybrid vigour also drops if you breed back to either of the parent breeds.

Our Labradoodle puppies are F1 generation (ie first cross between Labrador & Poodle), maximising hybrid vigor (or heterosis), and minimising inbreeding depression, etc. And have purebred parents with champion bloodlines/pedigrees.

The F1 (ie first generation) of Labradoodle puppies have more hybrid vigor than the second or so generation, are less likely to be more variable then some other generations, and also have the least inbreeding depression.

Another interesting scientific point to note about our F1 Labradoodles is that research has shown that these have increased longevity or rates of survival (eg research has shown up to 4 years longer), due to the absence of inbreeding (such as that occurring in purebred dogs). And the same research has shown that the higher the rate of inbreeding (eg in purebreds), the lower or shorter the longevity or survival rates. This relates to the term known as ‘inbreeding depression’, and which is
described in more detail at inbreeding depression and inbreeding depression.

And this may be due to the benefits from hybrid vigour, especially compared to the negative effects known as ‘inbreeding depression’ present in purebreds.

Unlike some breeders, we can guarantee the genetics of the puppies are solely Labrador/Poodle, as the parents of our Labradoodle puppies are purebred, and with pedigree papers. And this also ensures that they are definitely F1 puppies.

The term ‘hybrid vigor’ is used in various fields, such as breeding livestock, rabbits, aquaculture, plants, cats, dogs, etc.

And rather than just us giving you our opinion etc re hybrid vigor, we thought you may like to read information from other sources. So that you can make an informed choice or decision.

So, below are some relevant extracts re hybrid vigor, and links to their sources:

From MSN encarta online:

‘hy-brid vig-or

improved traits resulting from crossbreeding: the increased growth, disease resistance, or fertility seen in hybrid species.’

From Encylopedia Brittanica online:

‘Increase in such characteristics as size, growth rate, fertility, and yield of a hybrid organism over those of its parents.’

‘Plant and animal breeders exploit heterosis by mating two different purebred lines that have desirable traits. The first-generation offspring generally show, in greater measure, the desired characteristics of both parents. Since this vigour may decrease if the hybrids are actually mated together, the parental lines must be maintained and crossed for each new crop or group desired.’

From Merriam-Webster Online Dictionary:

‘heterosis

the marked vigor or capacity for growth often exhibited by crossbred animals or plants — called also hybrid vigor’

From report by CSIRO:

“The benefits of hybrid vigor only appear in crossbred animals that have parents of completely different breeds.”

From a transcript of the Senate:

“veterinarians recognize the concept of ‘hybrid vigor,’ especially in first generation hybrids”

From United States Department of Agriculture, University of Arkansas, and County Governments Cooperating:

“The highest level of hybrid vigor is obtained from F1’s, the first cross of unrelated populations.”

“Hybrid Vigor - An increase in the performance of crossbred animals over that of purebreds, also known as heterosis.”

So, there should be little (if any) doubt that the first generation (ie F1) Labradoodles have the maximum hybrid vigor and the least inbreeding depression compared to other generations etc.
