First 7 Days Post-Spay/Neuter
Day of Surgery
- DO NOT feed in the morning (anesthesia)
- After surgery, offer only small sips of water (4-6 hours)
- After full recovery (~6-8 hours): small portion of bland food
Evening: ¼ of regular portion. Boiled chicken + rice (50/50) OR recovery diet. Do not introduce new food.
Days 1-2: Gentle Diet
- Half portion (50%)
- Bland, low-fat
- 3 small meals daily
- Plenty of water
Recipe: 70% cooked white rice + 25% cooked chicken breast + 5% cooked carrots.
Commercial options: Hill's i/d, Royal Canin Recovery, Purina ProPlan EN.
Days 3-4: Increased Portions
- 70-80% of regular portion
- Continue bland food
- 2-3 meals daily
Warning signs: prolonged loss of appetite (48+ hours), vomiting, incision redness/discharge, lethargy → contact vet.
Days 5-6: Gradual Return to Regular Diet
- Day 5: 50% bland / 50% regular
- Day 6: 25% bland / 75% regular
- Day 7: 100% regular
From Day 7 Onward: Preventing Weight Gain
Metabolism slows down (males ~10-15%, females ~15-20%). Dogs can gain 1-3 kg (2.2-6.6 lbs) within 2-6 months.
- Reduce portion by 10-15% (weigh food)
- Switch to a spay/neuter formula (e.g., Royal Canin Sterilised, Hill's Light)
- Maintain exercise — gradual return after 7-10 days, normal activity after 14 days
- Monthly weight checks
Treats
- Significantly reduce treats during the first week
- From Day 7, offer only normal quantities
- "Sympathy" extras = guaranteed weight gain
Nutrients to Support Wound Healing
- High protein
- Zinc (usually sufficient in complete diets)
- Omega-3 — fish oil
- Probiotics (if on antibiotics)
Special Considerations
- Overweight: 20% reduction, switch to 'Light' formula from week 2
- Senior: slower recovery (10-14 days), warm food
- Brachycephalic breeds: higher anesthesia risk, elevated feeding
- Puppy spay/neuter (under 6 months): continue puppy food until 12 months
Warning Signs
🚨 SEEK IMMEDIATE VET ATTENTION IF: incision is red/swollen/discharging, persistent vomiting, no eating for 48 hours, lethargy, blood in urine/stool, pain
