Zinc Neutering is a quick and simple procedure that has to be precisely executed to avoid adverse reactions. The key is to avoid any leakage out of the testicular parenchyma into the subscrotal space—as the compound is not readily absorbed through the thin scrotal skin. Here are highlights of the injection technique that are stressed in all training:

1. Careful qualification exam including testicle and scrotal health review.

2. Correct measurement of testicles with a caliper to determine dosage as the foundation of the procedure.

3. While Zinc Neutering is not a sterile procedure, proper disinfection using a non-irritating Chlorhexidine solution diluted (10:1) and proper needle handling to minimize bacteria introduced into the testicle.

4. Use of 28-gauge or finer needles to ensure a virtually painless procedure, to minimize trauma, and to avoid dog movement during injection. It reduces the possibility of an itch or irritation in the area later.

5. Using a separate needle to withdraw product to ensure the injecting needle tip is dry and does not introduce any Zinc Gluconate into the subscrotal space.

6. No aspiration to minimize trauma as this is not an intravenous procedure.

7. Holding the scrotal skin tight over the testicle without putting pressure on the testicle to ensure clear path into the testicle avoiding spills into the subscrotal space.

8. Precise selection of site entry above the caput epididymis and correct needle length to deliver Zinc Gluconate into the center of the testicle--targeting the rete testis and minimizing chances of leakage.

9. Slow injection technique ensures the pressure sensors inside the testicle are not triggered. It makes the procedure painless for the dog and avoids testicular contraction that may leak the product out of the parenchyma into the subscrotal space.

10. Slow release of the testicle during the procedure and a distinct pause of three seconds at the end of each injection ensures pressure equalization inside the testicle as it receives the zinc neutering solution.

11. Quick and simultaneous release of the needle and the testicle after the procedure creates natural seal at the injection-site.

Training and Certification Protocol For Veterinary Professionals

To get Trained to Inject:

Observe 1 dog zinc neutering as a group, do one under 1-1 supervision, one under shared supervision, and teach one. Overall three dogs in addition to the demo dog.

To get Ark Certified:

Zinc neuter twenty dogs, send in the data sheets, apply for certification

To get Ark Advanced Certified:

Zinc neuter fifty dogs, send in the data sheets, apply for advanced certification

To get Ark Master Certified:

Zinc neuter one hundred dogs, send in the data sheets, apply for master certification

Finally, to become a Ark Master Trainer, a special half-day instruction is required beyond the the master certification. One does not have to be an Ark employee to become an Ark Master Trainer.
