  3. Theobromine in chocolates, a substance similar to caffeine, can kill the dogs, or at the very least make them seriously ill.
  4. The tallest dogs are the Great Dane and the Irish wolfhound. The smallest dogs are the Chihuahua, Yorkshire terrier and Toy Poodle.

    Very interesting facts, Valli.
    I especially like no. 6, although I wouldn’t want to have one that big.

    Three thousand four-hundred pounds is more than the weight of my SUV. I’m guessing you need a decimal point in there…

    Wikipedia lists Zorba as, quote, “over 315lb”

    Cheers!

    Yeah.. that was a mistake, I didnt realize till it was published. A decimal needs to be put there…

    Interesting piece. My 10 pound dog gives me a run for the money.
    I would not want to feed Zorba or walk him or her. But I bet no one would mug you. LOL

    Those were very interesting facts! But I really disliked the last 2, they were just cruel. I reckon the suicide one seemed the worse. I reckon no animal should be sent off to suicide itself. If it was so helpful why didn’t people do it. I don’t know what put the idea into the people who sent those dogs. People should suicide themselves if they think dogs should do it. Because the same reasons they would say why, would probably be the same for a dog only a bit different. But anyway the rest I liked.
