Other Important Notes

  • Surgery is available for cats and dogs only, and must be scheduled in advance by calling our Client Services staff at (302) 571-0111 or (888) DHA-SPAY. We cannot book appointments via email at this time.
  • You may bring a maximum of 3 animals per surgery day.
  • Animals must be at least 4 months old, but no more than 7 years old.
  • Animals must weigh at least 4 pounds, but no more than 50 pounds. Dogs that weigh over 50 pounds may be subject to an over weight fee, or may be turned away at the discretion of the veterinarian performing the surgery. Please note that there is limited space available for dogs over 30 pounds, so please plan to schedule an appointment well in advance if you have a large dog.
  • Animals must be able to be safely handled by medical staff; aggressive animals cannot be accepted for surgery.
  • Animals in the earliest stage of pregnancy CAN be scheduled for surgery, but an animal that is lactating (producing milk) can NOT have surgery until lactation has stopped.
  • Cats in heat CAN be scheduled for surgery without incurring an additional fee. Small dogs (up to 30 pounds) in heat MAY be scheduled, at the discretion of the veterinarian performing the surgery, for an additional fee. Large dogs (31 to 50 pounds) in heat can NOT be scheduled until the heat cycle is finished.
  • Dogs have to be tested negative for heartworms to undergo surgery. Heartworm testing is available on the day of surgery at an additional cost.
  • Animals must be free of bite wounds. Animals with bite wounds will be reported to the Delaware Department of Health’s Rabies Control Office.
  • Animals that are known to have impaired kidney and/or liver function, or pre-existing health conditions such as a heart murmur or seizures, cannot have surgery at DHA. This is for the safety, health, and well-being of the animal. Due to the high volume and low cost nature of DHA’s spay/neuter program, animals are not physically examined prior to surgery. Additionally, we do not offer what is called “pre-anesthetic bloodwork”. This bloodwork looks at key values of liver and kidney function. These organs are very important to processing anesthesia in the animal’s body.
  • The following breeds are also considered high-risk surgery candidates and cannot have surgery at DHA:


Brachycephalic breeds (pushed-in faces):

Bulldogs (English and French)

Dolichocephalic breeds (sighthounds):

Italian Greyhounds
Rhodesian Ridgebacks
Afghan Hounds


Brachycephalic breeds:


Exceptions to the DHA spay/neuter program eligibility requirements/restrictions or program procedures are made on a case-by-case basis with approval from the Veterinary Services Coordinator and/or staff veterinarians.
