Gibson, The World’s Tallest Dog Dies From Cancer
We’ve covered Gibson on these pages before. Well, you would, wouldn’t you. The world’s tallest dog is something we’re likely to cover! Sadly, he has passed away from cancer. A statement released today confirmed that the world’s tallest dog had been put to sleep last Friday.
Gibson was just 7 years old when he died.

In April 2009, Gibson was diagnosed with osteosarcoma, a form of canine bone cancer, which led to the amputation of his front right leg. The surgery was performed to prevent the cancer from spreading, and early tests showed positive results. After the surgery, Gibson received follow up chemotherapy treatments as a precaution.
Last week, Sandy Hall, Gibson’s owner, learned that the cancer had spread to his lungs and spine, at which point Gibson’s doctor stated that there was no other medical treatment that would save Gibson.
“Last week Gibson began having trouble using his back legs. X-rays showed that the cancer had spread to his spine and his lungs. Ms. Hall made the very difficult decision based on her concern and love for Gibson to have him humanely euthanized. Gibson died peacefully in the loving arms of Ms. Hall,” said Dr. Peter Walsh, Gibson’s veterinarian.

This is so sad. But all in all, Great Danes as well as other giant breeds, have a shorter lifespan. My condolences to his owner. It is so hard to let them go, but it is also the true test of an owner’s love for their dog to be able to let them go when it is time.
I would be curious to know if Gibson was neutered and at what age. New studies show that there is a connection between neutering prior to the dog achieving full maturity both in ‘legginess/heigh’, and to bone cancer. Just curious…

Sad, but I do not think any big dog could do well on three legs.
