Spring is an exciting time for horse owners—longer days, warmer weather, and the promise of lush green grass. But the transition from winter to spring turnout requires careful planning to keep your horse healthy and safe. This comprehensive checklist will help you prepare for grass season and avoid common spring pitfalls.
Why Spring Transition Matters
The shift from winter to spring brings significant changes that affect your horse's health:
- Rich spring grass high in sugars (laminitis risk)
- Sudden diet changes from hay to grass
- Increased activity and energy levels
- Shedding winter coats
- Muddy, wet conditions
- Parasite lifecycle reactivation
A gradual, well-planned transition prevents digestive upset, laminitis, and other spring health issues.
4-6 Weeks Before Turnout
Health Check and Vaccinations
- Schedule a vet check: Ensure your horse is healthy and ready for increased activity
- Update vaccinations: Tetanus, flu, and other core vaccines should be current
- Dental check: Spring is ideal for routine dental work before grass season
- Blood tests: Consider testing for Cushing's (PPID) or metabolic issues in at-risk horses
Parasite Control
- Fecal egg count: Test to determine worm burden
- Strategic worming: Worm based on test results and your vet's advice
- Plan rotation: Rotate horses between paddocks to break parasite lifecycle
Body Condition Assessment
- Score body condition: Aim for 5-6 out of 9 before grass season
- Weight management: Overweight horses are at higher laminitis risk
- Adjust feeding: Reduce hard feed if your horse will gain weight on grass

2-4 Weeks Before Turnout
Hoof Care
- Farrier visit: Ensure hooves are in good condition before increased activity
- Check for thrush: Treat any infections before turnout
- Consider studs: If fields are still slippery
- Discuss shoeing: Some horses benefit from being barefoot in summer
Field Preparation
- Walk the field: Check for hazards, holes, and damaged fencing
- Repair fencing: Fix any weak spots or broken posts
- Check gates: Ensure they open, close, and latch securely
- Remove debris: Clear any rubbish, branches, or dangerous items
- Test water supply: Ensure troughs are clean and filling properly
- Assess shelter: Check field shelters for damage and safety
Pasture Management
- Assess grass growth: Is it ready for grazing?
- Plan grazing areas: Consider strip grazing or rotation
- Identify high-risk areas: Note where grass grows fastest (usually sunny slopes)
- Prepare sacrifice areas: Set up grass-free zones for high-risk horses
1-2 Weeks Before Turnout
Rug Transition
- Reduce rug weight gradually: Don't remove rugs suddenly
- Monitor weather: Be prepared to adjust based on temperature
- Check rug condition: Repair or replace damaged turnout rugs
- Wash and store winter rugs: Clean before storing for summer
Grazing Muzzle Preparation
For horses at laminitis risk:
- Introduce the muzzle: Let your horse wear it for short periods in the stable
- Check fit: Should not rub or restrict breathing
- Practice removal: Ensure you can remove it quickly if needed
- Have spares: Muzzles can break—have a backup
Fitness Building
- Increase exercise: Gradually build fitness before full turnout
- Vary work: Include hacking, schooling, and groundwork
- Monitor soundness: Watch for any lameness as activity increases
Week of First Turnout
Final Health Checks
- Check vital signs: Temperature, pulse, respiration should be normal
- Examine legs: Feel for heat, swelling, or sensitivity
- Check digital pulse: Should be normal (not bounding)
- Assess movement: Watch for any stiffness or lameness
Equipment Preparation
- Fit turnout rug: Ensure it's appropriate for the weather
- Apply fly protection: If flies are already active
- Check headcollar fit: Should be secure but not tight
- Consider boots: Turnout boots can protect legs in muddy conditions
The Gradual Turnout Plan
Never turn horses straight out onto lush spring grass. Follow this gradual introduction:
Week 1: Introduction
- Day 1-2: 15-30 minutes on grass
- Day 3-4: 30-45 minutes on grass
- Day 5-7: 45-60 minutes on grass
Week 2: Building Up
- Day 8-10: 1-2 hours on grass
- Day 11-14: 2-3 hours on grass
Week 3-4: Extended Turnout
- Gradually increase: Add 1-2 hours every few days
- Monitor closely: Watch for any signs of digestive upset or laminitis
- Adjust as needed: Slow down if your horse shows any issues
High-Risk Horses
For horses prone to laminitis or metabolic issues:
- Use a grazing muzzle from day one
- Limit turnout to 2-4 hours daily, even long-term
- Turn out during lower-sugar times (late afternoon/evening)
- Consider a track system or sacrifice area

Daily Monitoring During Transition
What to Check
- Digital pulse: Should remain normal (not strong or bounding)
- Movement: Watch for any stiffness, pottery gait, or reluctance to move
- Droppings: Should remain normal consistency (not loose)
- Behaviour: Note any changes in temperament or energy
- Body condition: Monitor for rapid weight gain
- Legs: Check for heat, swelling, or filling
Warning Signs to Watch For
Contact your vet immediately if you notice:
- Increased digital pulse or heat in hooves
- Reluctance to walk or pottery gait
- Shifting weight from foot to foot
- Loose droppings or colic signs
- Excessive sweating without exercise
- Rapid weight gain or cresty neck development
Feeding During Transition
Adjusting Hard Feed
- Reduce concentrates: As grass intake increases, reduce hard feed
- Maintain forage: Continue providing hay, especially overnight
- Balance nutrition: Ensure vitamins and minerals are adequate
- Monitor weight: Adjust feeding to maintain ideal body condition
Water Management
- Ensure constant access: Fresh, clean water at all times
- Check consumption: Horses should drink 20-40 litres daily
- Clean troughs regularly: Prevent algae and contamination
Companion Management
Introducing New Companions
- Introduce gradually: Over the fence first, then together
- Supervise initially: Watch for aggressive behaviour
- Provide space: Ensure the field is large enough for all horses
- Multiple water sources: Prevent dominant horses blocking access
Herd Dynamics
- Observe interactions: Ensure no horse is being bullied
- Check all horses: Submissive horses may hide injuries
- Provide multiple feeding areas: Reduce competition
Ongoing Spring Management
Weekly Tasks
- Walk the field and check fencing
- Clean water troughs
- Remove droppings (reduces parasite burden)
- Check all horses for injuries
- Monitor grass growth and adjust grazing
Monthly Tasks
- Assess body condition scores
- Review and adjust feeding plans
- Check rug fit and condition
- Evaluate pasture condition
- Plan field rotation
Equipment Checklist
Essential Items
- Appropriate weight turnout rug
- Well-fitting headcollar
- Grazing muzzle (if needed)
- Fly protection (mask, rug, spray)
- First aid kit
- Hoof pick
- Thermometer
Field Equipment
- Clean, functioning water trough
- Field shelter in good repair
- Secure fencing
- Safe gates with working latches
Record Keeping
Keep a spring transition journal:
- Date and duration of each turnout session
- Daily observations (movement, behaviour, droppings)
- Any changes to feeding or management
- Weather conditions
- Any concerns or issues
This helps you identify patterns and plan better for next year.
Final Thoughts
A successful spring turnout transition requires planning, patience, and careful monitoring. By following this checklist and adjusting the timeline to your individual horse's needs, you'll minimize risks and set your horse up for a healthy, happy grass season. Remember: it's better to go slowly and prevent problems than to rush and deal with laminitis or colic.
Every horse is different—some will transition easily while others need more careful management. Trust your instincts, monitor closely, and don't hesitate to consult your vet if you have concerns.
