The Wolf In Your Living Room

ALASKAN MALAMUTE

Martin Clunes two part special called “A Man and His Dogs” is a must see. Clunes is a dog lover, English actor and comedian.

“Martin Clunes sets off on a world wide adventure to discover how close the domestic dog is to its ancestor the wild wolf in a fascinating two-part documentary.
 
The Doc Martin star takes a wry and witty look at why we are prepared to share our homes with dogs who are genetically still 99.8 per cent like wolves.”
 
He explores the close connection between dogs and wolves traveling to Yellowstone National Park to catch a glimpse of a wolf pack. He visits Australia to view Dingoes in the wild.
It’s a fun two hours and shows how close dogs and wolves really are. After watching this special it makes it even harder to understand how people can hate wolves, when in reality our beloved dogs are domesticated wolves.

Tapeworms and Wolves OH MY!!

May 16, 2010

The anti-wolfers are raging with the NEXT big wolf scare issue.

They’ve just made a startling discovery. Are you ready? Some wolves carry tapeworms. OMG what a shock!! Canines carry tapeworms??

I hate to break it to all the haters foaming at the mouth about tapeworms but DOGS carry tapeworms, so do foxes and coyotes.

CANINES carry tapeworms!

There are 72 million dogs in the United States alone and many of them carry tapeworms. At most there are 5500 wolves in the lower forty-eight, if you combine the Northern Rockies and Great Lakes wolf population.

So if wolf haters want to get worried and scared about tapeworms or the big scary Latin word they like to throw around, Echinococcus granulosus, then they better start worrying about the canines they already live with, since they are far more likely to come in contact with dogs then wolves.

Does it ever end with these people? Talk about hysteria. How long have we been living with dogs??

Here’s the spine-chilling details. Better break out your dog worming medications!!

Posted on October 8, 2008 by Maureen Anderson

Echinococcus granulosus is a tapeworm of dogs that causes a condition known as hydatid disease or hydatidosis in humans.  The parasite is found in many parts of the world, and is very common in some regions of southern South America, the Mediterranean, the Middle East, southwestern Asia, northern Africa and Australia.  To the best of our knowledge, E. granulosus does not occur in southern Ontario, but it is present in other parts of Canada including the western provinces and northern Ontario.  A related, but much nastier, tapeworm called Echinococcus multilocularis is much less commonly found in North America. (*which is carried in foxes, coyotes, dogs and cats.)

A previous Worms & Germs post described what is known as the sylvatic cycle of Echinococcus granulosus, which is thought to be a common route of infection for dogs in Canada.  In the sylvatic cycle, dogs become infected with Echinococcus by eating the internal organs (usually lungs and liver) of wild game such as moose and caribou.  The dogs then pass tapeworm eggs in their stool, which can cause infection in other wild animals (thus continuing the cycle) or in people who accidentally swallow the eggs.  In humans, Echinococcus forms slow-growing cysts (called hydatid cysts) in different organs of the body which can be very difficult to remove or treat in some cases.

Echinococcus also has a pastoral or domestic cycle.  In this cycle, dogs acquire the parasite by eating the internal organs of infected sheep, and sometimes other livestock such as cattle and swine.  This cycle is potentially very important in areas where there is a lot of sheep farming.  In some areas of Latin America, 20-95% of sheep at slaughter may have evidence of hydatid cysts in their organs.

It is much more difficult to tell when a dog is infected with Echinococcus compared to other tapeworms such as Taenia or Dipylidium.  An adult Echinococcus is tiny – only a few milimetres long (see picture right), very unlike the long, stringy white tapeworms that most people picture.  Dogs can carry hundreds, even thousands of these tiny tapeworms without showing any signs of illness at all.  The eggs can sometimes be difficult to detect on fecal examinations, and when they are seen they cannot be differentiated from Taenia eggs.  Nonetheless, this is still the best way to detect infection, so fecal examinations should be performed regularly.

Remember:

  • In areas where Echinococcus is known to exist, it’s important to have your veterinarian perform fecal examinations on your dog’s stool more frequently than the usual once-a-year, because of the serious zoonotic potential of this parasite.
  • Always wash your hands well after handling dog stools.
  • Do not let your dog eat uncooked meat, or the organs from farm animals or wild game.

Tiny Pooches Descended From Middle Eastern Gray Wolf

What does a genetic study on small dogs reveal? Surprisingly our cute little lap dogs probably originated in the Middle East some twelve thousand years ago, the direct descendants of the Middle Eastern gray wolf. The theory is smaller wolves were domesticated because they’re easier to manage in the home.

All small dogs, normally weighing 20 pounds or less, share the variant of IGF1 also found in Middle Eastern gray wolves, the scientists discovered. This means the gene must have surfaced early in the history of small dogs, but after dogs in general were first domesticated.

It all comes back to wolves. If it wasn’t for them we wouldn’t have small dogs or any dogs for that matter. Many of the qualities we love in our dogs were gifted to them by their direct ancestor, the wolf.

I wonder if people that hunt wolves think about that when they look through their scopes and aim to kill a wolf? If they don’t, they should.

From Science Daily:

Small Dogs Originated in the Middle East

ScienceDaily (Feb. 23, 2010) — A genetic study has found that small domestic dogs probably originated in the Middle East more than 12,000 years ago. Researchers writing in the open access journal BMC Biology traced the evolutionary history of the IGF1 gene, finding that the version of the gene that is a major determinant of small size probably originated as a result of the domestication of the Middle Eastern gray wolf.

Melissa Gray and Robert Wayne, from the University of California, Los Angeles, led a team of researchers who surveyed a large sample of gray wolf populations. She said, “The mutation for small body size post-dates the domestication of dogs. However, because all small dogs possess this variant of IGF1, it probably arose early in their history. Our results show that the version of the IGF1 gene found in small dogs is closely related to that found in Middle Eastern wolves and is consistent with an ancient origin in this region of small domestic dogs.”

Previous archeological work in the Middle East has unearthed the remains of small domestic dogs dating to 12,000 years ago. Sites in Belgium, Germany and Western Russia contain older remains (13,000-31,000 years ago), but these are of larger dogs. These findings support the hypothesis put forward by Gray and colleagues that small body size evolved in the Middle East.

Reduction in body size is a common feature of domestication and has been seen in other domesticated animals including cattle, pigs and goats. According to Gray, “Small size could have been more desirable in more densely packed agricultural societies, in which dogs may have lived partly indoors or in confined outdoor spaces.”
