Is Spaying or Neutering Worth It in Massachusetts?
The $390 upfront cost prevents far more expensive health issues later. The math is straightforward:
- Prevents pyometra (uterine infection): emergency surgery costs $1,500–$5,000 in Massachusetts.
- Reduces mammary tumor risk by 99% when done before the first heat cycle.
- Eliminates testicular cancer and reduces prostate problems in male dogs.
- Prevents unwanted litters: raising a litter to 8 weeks costs $800–$2,000+ in vet care, food, and supplies.
