Compare Dog Breed Characteristics
What breed of dog is this?

We adopted a sweet girl at a local shelter, she thought it was part Akita and part Shepherd. I can see some of Akita features compare it with our purebred Akita, but I wonder what other race they are. Any ideas? There are pictures of her on the link (if it works) http://search.petfinder.com/petnote/displaypet.cgi?petid=11697777

Dog has gorgeous eyes. due to the difficulty of the skin and the shape of the head, I see some American Staffordshire Terrier, Staffordshire Bull Terrier or (pit bull) in it.

Dog Evolution: How the dog is changing so quickly to new species

The eminent evolutionist Charles Darwin postulated that the evolution took place gradually, slowly browsing through the wire covering the time period of several generations. At its most basic evolutionary changes occurs in response to environmental changes, a dynamic that was quite logical Why, after all, is a biological body to undertake the costs morphological and genetic changes, if no appeal to her? Just watch the crocodiles to see a species that has changed little more than 40 million years and yet still day is very well suited to excel in their particular ecological niche!

The dog is also a successful example of evolutionary success. Descendant of wolves There are approximately 400 million dogs in the world against 400, 000 wolves to say wolves are more likely than other dogs today by a multiple of 1000. In fact, when you have dogs in mind when they made their debut in the land as a separate species (widely accepted as anywhere between 15,000 to 10,000 years Although the jury is still out on when he appeared for the first times), then the evolution of the dog in the 400 breeds that exist today is somewhat Unless a miracle! Fifteen thousand years on the evolutionary ladder things is very little time!

High selectivity?

Popular opinion in favor the dog is changing so rapidly since it was selectively bred by humans for specific characteristics that define different breeds of dogs. Although a great proof that dogs existed 8,000 years ago, evidence of its existence and beyond about 15,000 years ago is rare at best. Which begs the question, how could a species like the dog to enter their own so well in the space of just 5000 – 7000 years?

This can be credited to selective breeding by mankind; Mesolithic man certainly did not have time, tools, knowledge, intelligence, or a wolf population large enough to carry a mild selective trait breeding program successful. There enough factual evidence, but many breeds of dogs existed a few years ago and in 3000-4000 the Roman era many breeds are common today.

The sweetness Feature coincided with the ears, barking and coat color change!

How the morphology of dog and the genetic constitution changed so radically from that of the wolf in a short time has become more mysterious. However, as Often in such cases, the experimental research conducted on a completely different animal revealed the key to how the change took place. In the 1950s, a Russian scientist named Dmitri Belyaev began selectively breeding silver foxes (Vulpes vulpes) only mildly. The first goal experiment was to produce a fox that was more accessible and manageable by humans who have greatly contributed to the reproduction and breeding of these animals for their fur.

Farmers know the problem is that although the animals they were dealing with had been raised in captivity for 50 years by any stretch of the imagination could be considered safe not tame, the way a dog! Foxes hinder often their owners, sometimes even little, and sometimes the animals were injured in an effort to escape his captors.

Belyaev foxes and his colleagues and selected which showed the lowest fear / shyness of the people for their breeding program, his goal was to selectively breed for the trait to tame. With successive generations of selective breeding foxes became tamer and Tamer fox so that by the eighteenth generation, had grown up all the characteristics of a domestic dog. Foxes very close people, climb make a U-turn to get tickled his belly and even responded to their names.

Perhaps the most surprising aspect of the breeding program selective, that foxes seemed more foxes, but looked and acted like dogs. The fox coats and skin are not very characteristic of money requested by the fur industry, but were in black and white overo instead. In addition, the tails of foxes to its curly ears were flexible and above all animals, even barking like dogs! Dmitry Belyaev had neither requested nor race of these characteristics, but the Performing together again!

A survey on Back unexpected side effects have revealed that raising the sweetness triggered a cascade of hormonal changes in animals. It was noted that the tame foxes had significantly lower levels of adrenaline which explains their docility (reduction to flee or fight reflex), but does not explain the other changes observed. However, it was not long Belyaev and his colleagues have linked the action of the hormone adrenaline a pathway to melanin, a hormone that plays an important role in color of animal fur.

In short, selective breeding for docility of character left and stimulated a series of changes genetic animals in a surprisingly short time. Currently it is estimated that the wolf has been subjected to a similar evolution dog evolution in time home.

What breed rottweilers and children around?

I always wanted a Rottweiler, but have no experience with them. My Buddy was raised hunting dogs pork Great Dane x mastiff or pit bulls even know how to manage them. But I'm always worried about what would be. They a bad reputation and I wonder if it is a characteristic of race or if it's just bad blood lines, and if children are sick? How they compare with American bulldog? DJL thank you for your concern. I think getting married and having children atm, but I want a dog like my dog probably still be there when they marry and have children who want one that is good with them. Although this is, 10 years after the track.

I have six children and have led Rottweilers for over a decade. They are wonderful dogs, and if you choose a puppy health, well-educated parents have excellent temperament, stable, he or she will be excellent family dog. However, Rotter (like pit bulls and other breeds) have been careless breeding, and although it is easy to find almost anywhere Rottweilers, Rottweilers find GOOD is not so easy. Take your time and do all necessary research before choosing a puppy. Always meet the parents and ensure they are accessible and of good character. Also ensure that appropriate health checks were taken (OFA for hips is a must). Although Rottes tend to be very affectionate and loyal with their families, who are a breed warden, not a good option for the first time dog owners. Despite its size and strength, they do not need training hard and corrections, and closer to the manipulation loving, but firm. breeds of large dogs and giants have their own needs, and this http://www.the-puppy-dog-place.com/extra-large-breed-dogs.html page contains much information and advice on them. It is also important to realize that a big, strong as a Rottweiler dog might harm / Drop a child (or elderly, poor) unintentionally. For this reason, I personally do not recommend a Rotti for a family with young children or babies but with a lot of supervision and training can work. Some breeds of dogs that have proven to be excellent family dogs, and being good with children. You can see the links below for other options. Good luck with the ultimate race of your choice.
