No specific cause of decline
Thank you in advance to anybody who takes the time to read my question. My 12 year old girl passed away peacefully at home on Tuesday. I was full time caring for her and it was an absolute honour to care for her up to the end. She was my world.
In April 2025, she had a clean bill of health, the vet even noted how healthy she was for her age. In September 2025, I discovered a bump on her lip that was biopsied and it ended up being cancerous. Mast cell tumour or lymphoma was the diagnosis, but since treatment was similar and we were not opting for surgery, we didn’t confirm with more testing. After that, she just started to decline further. Her cognitive symptoms such as hiding under furniture began in January 2026, and by May 2026 she was spending her days on little to no sleep, speed walking around the house, terrified of steps, hiding under the bed, behind the toilet, nearly constant crying, and screaming into corners of the house. I took her to the vet multiple times. She was unresponsive to Selegiline (it actually made it worse), gabapentin (helpful in the past, but not for this), hemp oil, leaving a light on at night, walks before bed, etc. It was terrifying to see her suffering and we decided to let her go.
Now that it’s happened, I am in shock over how much she was suffering at the end. With no clear answer on what caused this, I’m left feeling so confused and heartbroken. What could’ve put her in this place within a year’s time?
