Antimicrobial Stewardship Guidelines for Companion Animal Practice
Updated: July 2025
Antimicrobial resistance (AMR) continues to rise globally, and veterinarians are on the frontlines of prevention. Companion animal practitioners have a critical responsibility to use antimicrobials wisely, ensuring effective treatments today and in the future.
This guideline outlines core actions for implementing antimicrobial stewardship (AMS) in small animal practice.
โ 1. Assess Before Prescribing
Before initiating antimicrobial treatment, always:
- Conduct a thorough clinical examination.
- Evaluate whether the infection is bacterial and warrants antibiotics.
- Use cytology, culture, or other diagnostics where feasible.
- Educate clients on non-antibiotic management when appropriate.
๐ 2. Choose the Right Antimicrobial
Select an antimicrobial based on:
- Empirical evidence or culture and sensitivity results.
- Choosing narrow-spectrum drugs whenever possible.
- Avoiding critically important antimicrobials unless strictly necessary.
- Referencing national or regional antibiotic use guidelines.
๐ 3. Optimize Dosage and Duration
- Prescribe the correct dose and frequency based on species and weight.
- Use the shortest effective treatment duration.
- Monitor for adverse reactions or lack of response.
๐งผ 4. Promote Preventive Care
Reduce the need for antimicrobials by:
- Encouraging vaccination and parasite control.
- Supporting nutritional health and wellness.
- Improving dental hygiene and skin care routines.
- Educating pet owners on infection prevention at home.
๐ 5. Maintain Clear Medical Records
- Document diagnosis, treatment rationale, antimicrobial name, dose, and duration.
- Track repeated treatments or recurrent infections.
- Use reminder systems to follow up on chronic cases.
๐ 6. Ongoing Education and Quality Control
- Keep staff informed on emerging resistance trends.
- Conduct regular audits of antimicrobial use.
- Participate in continuing education (CE) on AMS.
- Consider adopting a clinic AMS policy for consistency.
