Short answer

Boric acid is used in insecticides like roach baits and ant killers. Store products in sealed containers in cabinets your dog cannot access. Teach 'leave it' commands. If your dog eats bait, call your vet immediately. Signs include drooling, vomiting, bloody diarrhoea, tremors or seizures. Do not induce vomiting — boric acid is corrosive. Bring the product container to the vet.

Why a 15 kg labrador needs extra vigilance

Larger dogs like your labrador can reach higher surfaces and chew through flimsy containers, making standard storage risky. Their strong jaws and curiosity mean even 'child-proof' lids may not deter them. Look for heavy-duty plastic bins with locking clasps, and place them on top shelves in a closed pantry or garage — not just under the sink where they can nose open doors.

Since labs are food-motivated, avoid bait stations that smell like treats. Gel baits or powders spilled during application are especially dangerous, as they stick to paws and get licked off later. After using any product, wipe the area with vinegar to remove residue smells that might attract your dog.

Teaching 'leave it' with high-value distractions

Start training with harmless items like toys before practicing near actual hazards. Hold a boring object (a pen) in one hand and a roast beef piece in the other — when your dog ignores the pen to look at you, reward with the meat. Gradually increase difficulty by placing baits under a clear container.

For persistent scavengers, keep a drag leash indoors so you can quickly step on it if they bolt toward something suspicious. Never punish after the fact — if they’ve already eaten bait, scolding hides the evidence you need for treatment. Instead, praise them for dropping items on command during drills.

Hidden dangers beyond the bait station

Check for alternative exposure routes: some laundry detergents, eyewashes, or homemade slime recipes contain boric acid. Your dog might lick freshly mopped floors or dig through trash for used bait containers. Even small amounts absorbed daily can build up to toxic levels over time.

Watch for early signs like excessive lip-licking or pawing at the mouth, which may indicate oral irritation before full vomiting starts. Labs often hide discomfort, so note any reluctance to eat their regular meals or unusual lethargy after being near storage areas.

Emergency substitutes when vet care is delayed

If you can't reach your vet immediately, offer ice cubes to soothe mouth irritation without risking further toxin absorption. Use a damp cloth to wipe gums if you see powder, but avoid forcing water into their mouth — this could push chemicals deeper into the throat.

Collect packaging remnants to show the vet exact ingredients and concentrations. Time matters: note whether your dog ate this recently or has been sneaking bits over weeks, as chronic exposure requires different blood tests than acute poisoning.
