Spay & Neuter

Delayed Spay/Neuter vs. Early Spay/Neuter

At MAMCO, we believe in doing what is best for puppies. Because of this it is essential that all dogs in our care are spayed or neutered. Breeding dogs actually shortens their lifespans and failure to spay or neuter can also lead to other health problems.

While we require that ALL of our dogs are spayed or neutered, new developments in veterinary medicine suggest that sterilizing a dog before 6 months of age can also lead to unnecessary health concerns. For this reason we prefer not spay or neuter our puppies until they are 6 months or older. However, the State of Colorado instituted a new statute, Statute 35-80-106.4, which requires all animals to be spayed and neutered prior to adoption: Read the statute by clicking here

While we do not agree with the new spay and neuter laws, and have worked to find loopholes that will allow us to postpone spay and neuters, several of our partner organizations are now requiring all dogs to be spayed or neutered prior to attending adoption events. Therefore, we have decided to comply with the law where “event” puppies are concerned. All of our dogs attending PetSmart and Petco adoption events will be spayed or neutered prior to attending the event.

For those adopters who prefer to have more autonomy in regards to their dog’s veterinary care, we will be adding another option for you that allows you to follow veterinary advice and wait to have the spay and neuter procedure completed.

Delayed Spay and Neuter Options

In the past MAMCO has listed available dogs one week prior to their available adoption date. With the new rules in place we will be changing this system and begin listing puppies when they’re six weeks of age. If adopters wish to place a $250 hold deposit on the puppy AND wish to have the spay or neuter postponed, we will have time to accommodate this request. During that time, we will take the puppy to one of our partner veterinarians for a check up. At that time, the veterinarian will write a letter postponing spay and neuter until a specific date. When the puppy is old enough to be adopted, we will facilitate the adoption at our office to avoid interfering with the rules and regulations of our partner organizations.

Spay and Neuter Deposit

We require a $300 deposit in the form of a check. We will NOT cash this check unless you fail to have your puppy sterilized by 6 months of age. Once your puppy has been spayed or neutered, send us a picture of the spay/neuter certificate via email. At that time we will void your check.

We realize that sometimes our partner veterinarians have a full schedule and that it can be difficult to get an appointment. If your spay or neuter appointment is delayed slightly, moving you beyond the 6 month date, DO NOT PANIC. Just send us an email to showing us the appointment date, and we will make a note in our system to hold the check until the appointment date.
