My 15 kg Labrador ate a whole 200g bag of snap peas in one go — is that too much?

Short answer

Yes, that amount is excessive and can cause stomach upset. A whole bag is a large, fibrous volume that can lead to gas, bloating, or soft stool. Watch for signs like a noticeably distended belly or diarrhea over the next 12 hours. Offer only water and a bland diet for its next meal, and call your own vet if it seems uncomfortable or won't eat.

How 200g overwhelms a Lab's digestion

That bag held about 60-70 peas — equivalent to four full cups of raw vegetation hitting his stomach at once. While not poisonous, this volume acts like a sponge, absorbing gastric juices and swelling. Labs are prone to bloat even without dietary indiscretions, and this much fibre creates perfect conditions for gas accumulation. Listen for hollow drum-like sounds when tapping his left flank.

The real concern is mechanical rather than toxic — imagine stuffing 15 socks in your washing machine. His stomach will try to compact this mass, potentially causing painful spasms. You might notice him standing with his back arched or reluctant to lie down on his usual side over the next six hours.

Why tomorrow's walk matters

All that fibre needs to move through approximately 20 feet of canine intestine. Without adequate water and movement, it can form a sluggish plug. Take him for gentle 10-minute walks every three hours (even at night) to stimulate peristalsis. Avoid vigorous play — a full colon makes torsion more likely in deep-chested breeds.

Check each stool for intact pea pods — their waxy coating sometimes prevents proper breakdown. Finding more than three whole pods in his output after 24 hours suggests his system isn't processing them effectively. Save a sample in a baggie to show your vet if diarrhea persists beyond two days.

Emergency signs in big dogs

Labs mask discomfort well, so watch for subtle changes like refusing second helpings at meals or drinking less water than usual. Press his left side gently — normal stomachs feel like a half-filled water balloon, not a taut basketball. Rapid shallow breathing when resting is more concerning than panting after exercise.

True vomiting (not just regurgitation) more than twice in an hour warrants an immediate vet visit. At 15 kg, he can dehydrate dangerously fast while still appearing "fine." Check his gums — they should be slick and bubblegum pink, not tacky or pale. Pinch the skin at his shoulders — it should snap back instantly.

Rebalancing after the binge

Skip his next scheduled meal entirely, then offer a bland diet of boiled white rice and skinless chicken (25% of normal portion) every four hours for a day. The starch helps bind excess water in his colon while giving his microbiome time to reset. Resist supplementing with pumpkin or other fibres — his system needs simplicity now.

Long-term, store veggies in elevated containers — Labs can open cupboards with their noses. If he counter-surfs for produce, try offering frozen green beans as a safer alternative. The satisfying crunch satisfies the same oral fixation with fewer digestive consequences when consumed in bulk.
