A liver tumor

On May 21, 2026, with a trembling voice, she explained in a video Instagram that Simon suffered from liver cancer. He had been hospitalized and placed in intensive care for several days, following a series of epileptic seizures; he had experienced 4 in the space of 5 hours.
6 months earlier, an ultrasound had led veterinarians to discover a mass in his liver, but they initially thought it was caused by his treatment with phenobarbital, prescribed for his epileptic seizures.
A subsequent examination showed that the tumor in question had increased in size. The priority for Isabel Klee was then concerned with preserving the quality of life of his 4-legged companion. She continued, despite everything, to welcome other dogs while taking care of Simon.

Isabel Klee published, on April 28, a book entitled “ Dogs, Boys, and Other Things I've Cried About » and in which she recounts her experience as a foster mother for dogs. Simon is, of course, one of the protagonists.
Woopets advice: what signs should alert you after an epileptic seizure in dogs?
After one or more attacks, certain symptoms require rapid veterinary consultation, especially in an elderly or already sick dog:
- Close attacks (more than 2 in 24 hours)
- Persistent difficulty walking or maintaining balance
- Unusual disorientation, visual disturbances, or abnormal behavior
- Prolonged loss of appetite or repeated vomiting
Even if the animal seems to be doing better between attacks, additional assessment (blood test, ultrasound, MRI, etc.) may be necessary to look for an underlying cause, particularly neurological or hepatic.
