I'm Dr. Sarah Martinez, DVM, and I've been practising veterinary medicine for 22 years.
I graduated summa cum laude from Cornell, completed my residency at UC Davis, and have treated over 8,000 dogs with lumps and bumps.
I also thought I understood "fatty tumours" completely.
Then my own dog Max got his first lump.
Max was a 6-year-old Border Collie mix with perfect genetics and flawless health records.
When I felt that first soft lump on his shoulder, I did exactly what I'd been trained to do: biopsy, confirm benign lipoma, reassure the owner.
"It's just a fatty tumour," I told my husband.
"Completely harmless."
I was dead wrong.
Over 18 months, Max developed seventeen more lumps.
Each biopsy came back "benign lipoma."
Each time, I followed protocol and reassured myself they were harmless.
By age 9, Max couldn't walk properly.
The lumps weren't just cosmetic - they were affecting his movement, his breathing, his quality of life.
I had to make the most heartbreaking decision of my career.
I had failed my own dog with everything I'd been taught.
