A few months ago we had to put our beloved 13 year old Springer Spaniel named Madison (or Maddy) to sleep after she bit our son. We loved her very very much and she was the sweetest dog ever (right up to the second she bit our son). It was really sad.
All we have left at this point is the lizard I have owned for many years named John Holmes. He is a Uromastyx and is the king of his 150 gallon tank.
lol - he has gotten me once or twice over the years when cleaning the tank. He used to be in the tank with a Chuckwalla who was also beautiful, but sadly that lizard died after about 4 years. Now he is alone in his world.
Yea, it was pretty crappy. Long story short, completely out of the blue she bit my son's ear and almost pretty badly. She was very old, going deaf and blind and he was playing on the floor and must have startled her. Before any of us could even move she lunged at him and started biting his face and ear. I jumped up in a crazy rage and was literally strangling the 40 pound dog with my bare hands and holding her above my head swinging her around and yelling. My wife was crying and then said our son's ear was bleeding. I had not seen that because he was turned away from me. I dropped the dog and grabbed him and brought him into our kitchen under bright light and his entire ear was bleeding from multiple places, obvious cuts, puncture wounds. etc. We took him to the hospital while her mother came over and took the dog to the Vet we use.
Luckily my son was basically ok and no long term damage. As much as we loved that dog there was really no choice at that point, especially with a newborn on the way a few months later at that time. Even the vet said with her age, ongoing medical problems, and fact she would now always be a "biter" - it would be hard to put her in a new home. For a dog it is almost like being a child molester. You can never shake the tag of being a dog that bit a child.
Was a sad day in our family, but luckily everyone was ok in the end.
