Colombianimals is a non-profit organization dedicated to controlling dog and cat overpopulation in Colombia through spay and neuter campaigns.

Days Left to Start the 2024 Training Program
The 2024 Veterinary Surgical Training Program has either started or ended. If you are interested in participating in the future, please add your name to our email list below.


It is for veterinarians who have already graduated and are practicing, and for veterinary students who have completed at least second year.

You can check out the program curriculum above, but to summarize, the focus of this program is training you on the flank (lateral) ovariohysterectomy (OVH) surgical technique.

Because this is a widely-used technique in HQHV (high quality, high volume) spay/neuter campaigns in Latin America, so, if you ever wanted to volunteer as a surgeon at a HQHVSN campaign in Latin America, you’ll want to be trained on this surgical technique. Plus, it’s a good skill to add to your professional toolbox!

You don’t have to pay for everything at once. There’s a schedule of payments, approximately one month apart. 

We encourage participants to raise funds for this project.

The lead veterinarian is Dra. Paula Rojas, a Colombian vet with 10 years of experience in HQHVSN. She’s bilingual and will lead the first week of training.

On the second week, Dr. Félix de La Rosa, who also has many years of experience with HQHVSN, will join us. Dr. Félix is not bilingual, which is why participants will take veterinary-specific online Spanish lessons before arriving in Colombia.

Not yet but it’s in our plans! We would love to provide RACE and CE credits to participants who complete this program.

Santa Marta, Colombia. Santa Marta is a city on the Caribbean coast of Colombia. The weather is tropical, averaging 32 C (90 F) year-round.
