Eligibility Criteria


To be eligible for the Penn Vet Shelter Canine Mammary Tumor Program, dogs must meet certain criteria:

  • Must be homeless or in foster care (the donations are based on helping homeless dogs; therefore, dogs that are already adopted from shelters cannot be enrolled through the shelter program)
  • Must be up-to-date on vaccines (including Rabies Vaccine)
  • Must be free of contagious disease prior to screening/enrollment. We therefore request that all potential candidates live outside the shelter environment for two weeks prior to presentation to Penn Vet for screening.
  • Must have at least one tumor at least 3 cm (1.5 inch) in diameter
  • All dogs must pass the initial pre-enrollment screening/staging before we officially enroll them in the program. This will ensure that they are systemically healthy enough to tolerate anesthesia and surgery and likely to benefit from participating in our program.
  • No dog with a history of or ongoing human directed aggression can be enrolled in this program. The purpose and goal of this program is that these dogs will be placed in permanent foster care/adopted so we can follow their clinical progression after their surgery.
  • Must agree to an autopsy if/when the dog dies so that cause of death and presence of metastatic disease can be determined.

  • brownie-in-sling2Follow-up information is extremely important for this program, therefore, the participating shelters as well as new foster parents/adoptive parents are asked to sign an informed consent agreeing to adhere to the follow-up visit schedule as described in the informed consent (every four months the first year, then every six months thereafter). All costs associated with the follow-up and monitoring will be covered by the funding. If the dogs develop additional mammary tumors (which happen in some dogs) the study will take care of this, too.
