A very important thing to consider about the relationship between wolves and dogs is that domestic dogs from a certain region share many physical similarities to wolves from that same location. These kinds of important similar traits have been seen far too often in the whole world for it to be caused by coincidence. In 1829 Sir John Richardson recorded that “the resemblance between the North American wolves and the domestic dog of the Indians is so great that the size and strength of the wolf seems to be the only difference”.

Some people have suggested that the fact that dogs bark while wild wolves only howl is proof that they are not related. This, however, is quite absurd since it is well recorded that any wild member of the canine family raised by a domestic mother will learn how to bark. It goes both ways as dogs allowed to run wild will forget how to bark. What people are witnessing is learned behavior, something common to many mammals. It is not a sign that the two species are not related.

The influence of the behavior of barking can’t, then, be regarded as an argument in deciding the issue concerning the origin of the dog. This opposition consequently fails, leaving us with the sensible choice of agreeing with Darwin, whose final hypothesis was that “it is highly probable that the domestic dogs of the world have descended from two good species of wolf (C. lupus and C. latrans), and from two or three other doubtful species of wolves namely, the European, Indian, and North African forms; from at least one or two South American canine species; from several races or species of jackal; and perhaps from one or more extinct species”; and that the blood of these, in some cases mixed together, flows in the veins of our domestic breeds.

    Lupus?Lyme disease?? whats going on?
    SYMPTOMS
    Pain, weakness, or numbness in the arms or legs, swollen joints everywhere, joint pain everywhere, dizziness -and everything literary spinning like I just got off a roller coaster-, jaw sharp stabbing pain, head ache, pressure in my head, blurry vision, problems with walking, Poor memory and reduced ability to concentrate [sometimes during a day I forget the first half of it completely], Heart pain, little hallucination -an object moved-, extreme fatigue……

    I would like to add that I had a baby 4 months ago, and that I have a dog who has lyme disease. I don’t know if it can spread via flees -I got bitten-. I know I havent been bitten by a tick -I also havent been out lately-. What you think
    I also have problems with concentration while talking
    Im a SAHM and I clean cook and take care my son the whole day.
    I have only 1 kid
    in addition I got so dizzy once I ended up falling on the ground.

      Sounds like a new Mom … do you have other kids at home … do you work … do you have anyone to help you out or are you doing it all? I have an 8 week old … I am all of these things and more. You should take a day and relax, we left the kids with Sister and Mother in law and took off for the amusement park. Everyone had a great day.

    How sick is my dog??
    I have a 12 y/o schnauzer (Simon) and he was diagnosed last month with lupus. We began steroid treatment because all his hair fell out. He has begun chewing on his skin, creating nasty hot spots and nothing keeps him from it but a cone! Now the vet is saying it could be something else. His skin has become extremely irritated and it almost looks like he is developing liver spots. I am taking him for a biopsy in two weeks. Has anyone else had a pet with these symptoms and/or possible diagnosis?

    What is the correct dosage of prednisone for an allergic Labrador Retriever?
    I have a very allergic chocolate Labrador Retriever. When he was 6 months old, he started with the allergy symptoms. He was losing his hair, scratching his paws and the base of his tail ext. It was later discovered that he is allergic to food. I put him in a hypoallergenic diet and he was cured (about 99 %) He is now 2 years old and he gets allergies from time to time. I was told that he maybe allergic to something else in the environment. The thing is, around two weeks ago, he started with severe allergy symptoms. I haven’t change his food and he is living in the same environment. The veterinarian prescribed him a tablet of 20mg of prednisone (steroid) every 12 hours for two weeks. That is 40mg of prednisone for a 87 pound dog. My father is a Rheumatologist and he deals every day with steroids that he prescribes to patients with Lupus. I told him about the dosage and he said that that was a huge dosage and that he doesn’t even prescribe half of that dosage for a full grown human being. My question is the following… Are dogs different to people when it comes to the amount given of medicine dosages? Is the dosage given to me by the veterinarian the correct one? And if not, what is the correct dosage if anyone knows? Thank You

    What are the chances of this being Lyme Disease?
    I got sick 6 years ago out of nowhere.
    I was extremely nauseous everyday and dizzy to the point the room was spinning.
    I couldn’t drive in cars anymore because I’d get motion sickness
    And I also developed anxiety that I never had before.

    For a whole year I could barely eat and never left my house.
    I was sick EVERYDAY (not vomiting but nausea etc.)

    After about a year and a half the symptoms got a bit better and I started doing the things I used to do.. eating more, going out etc.

    Then I started getting severe fatigue…no matter what I do, how much I sleep..I’m still DEAD tired.
    I have purple colouration under my eyes and they’re sunken in.

    All my symptoms are:

    Nausea
    Extreme Fatigue
    Dizziness/Lightheaded
    Weakness
    Purple toes (Raynauds)
    Poor healing
    Ringing in ears while trying to sleep
    Anxiety (Weird neck twitching)
    Tingling in toes/feet
    Shortness of breath
    Irregular heartbeat
    Pain behind eyes/Change of vision/Pressure in eyes
    Cloudy state of mind sometimes
    Stuttering when speaking sometimes
    Chronic runny nose
    Diarrhea/Constipation
    Alopecia (hair loss)
    Raynauds (purple toes)
    Sensitivity to light
    Cold/Hot flashes
    Poor balance

    The only thing is, I live in Ontario Canada.
    I’m not sure if there are many ticks around where I live.
    I also never had any sort of target rash that I can remember…but I was young I could have not even noticed.
    I did have alot of dogs and a outdoor cat that we let back inside.
    And I remember my cat having a large white tick that we had to pull of of it.
    But I also wonder if it is Lyme why didn’t my mom or brother contract it?

    Do you think this could be Lyme?

    I’ve been tested for Anemia, Diabetes, Lupus, Celiac, Thyroid issues etc.

    My dog has canine lupus??!!?
    Well we know my dog has canine lupus. I want to know what kind tho.. Dle or sle? The only symptoms are his nose is all flaky an crackly and he has bad eye boogers, and his joints get stuck a lot so he has to hop on three legs for a while then it goes back. I am really heartbroken that he even has lupus.. :'( well he is a mini american eskimo, and his names cody. He has a best friend named anjin. (on Jin) we also own him, we have to give him like fish oil every day. The vet told us to put sunscreen on his nose but we do it then he goes and rubs it off in our grass. So I don’t know what to do about that. Pleaseeeeeeeeeeeee help!!? Thank you so so so so much on advance. 😉

      I am so sorry about Cody–this is a very unusual disease in dogs, my son’s pit bull had it but it doesn’t seem to be fatal, she lived for a long time with it. You are doing everything right except you must protect him from the sun somehow. His nose will get worse and turn into big sores if you don’t. Can you keep him in and just walk him on a leash a couple times a day? If you do that, you can put the sunscreen on his nose and keep him from rubbing it off. And this has the added benefit of keeping him from too much exposure. I would definitely recommend this. It’s important to protect his nose.

      Good luck to you and best wishes from Lucie the Eskie and me!! We hope Cody will be all right soon–he may never get absolutely well but he can live a long time and be happy anyhow…
