  • Surgery or surgical removal of cancerous tumors
  • Treatment through radiation to kill the cells
  • Chemotherapy, which is generally well-tolerated in dogs. They hardly ever get sick, & loose hair.
  • Immunotherapy or anti-disease vaccine to strengthen the immunity system against an invasion of the problem.
  • Stem cell transplants in dogs who have been tested with blood-related cancer.

Cost to treat the pet:-

The cure varies depending on the disease traits. There’s the symptomatic testing that is required preceding doing any kind of therapy, and that can go from $200 to $1,000.
