Why a 7 kg terrier fixates on the coriander plant
Terriers are bred to hunt by scent, and your potted coriander emits volatile oils that trigger their investigative instincts. At this size, even a small plant represents a significant temptation—not because it's dangerous (the leaves are safe), but because allowing the behavior could lead to chewing on toxic houseplants later. The goal isn't just protecting the herb, but establishing garden boundaries for his safety.
Start by placing the plant temporarily out of reach—on a high windowsill or behind a baby gate—while you work on training. This removes the temptation during the learning phase. Terriers respond best to consistent routines, so schedule short training sessions before his regular mealtimes when he's most focused. Keep sessions under five minutes to match his attention span, ending on a success.
Tailoring 'leave it' for plant sniffers
Traditional 'leave it' training often starts with food, but for plant-focused dogs, begin with non-edible items that mimic leaves. Crumple a piece of paper or fabric, say 'leave it,' and cover it with your hand. The moment he looks away, click or say 'yes!' and reward with a high-value treat like liver paste on a spoon. Gradually progress to real (safe) leaves on the ground before attempting the potted plant.
When introducing the actual coriander plant, keep him on leash at first for control. Let him sniff while saying 'leave it,' then gently guide him back with the leash if he tries to nibble. Reward any voluntary disengagement, even accidental. Terriers can be stubborn, so patience is key—it might take weeks of daily practice before he reliably ignores the plant off-leash.
When curiosity wins: post-nibble care
If he does sneak a bite, don't scold—terriers often interpret attention as reward. Simply remove him from the area without fanfare. Coriander leaves may cause mild stomach upset in sensitive dogs, so watch for gagging or lip-licking over the next few hours. At seven kilograms, eating more than a few leaves could lead to soft stool, but true toxicity isn't a concern.
Check the plant for damage—terriers often dig at roots or knock over pots in their enthusiasm. Repot in a heavier ceramic container if needed, and consider sprinkling citrus peels around the base as a natural deterrent. Their strong scent is unpleasant to most dogs yet harmless to plants. Just refresh the peels weekly as their aroma fades.
Making obedience more rewarding than plants
Terriers need appropriate outlets for their digging and chewing urges. Provide a designated 'dig box' filled with sand or soil (hide treats in it to encourage use) and rotate chew toys to maintain interest. When you see him investigating the coriander, redirect to these approved activities instead. Praise heavily when he chooses them voluntarily.
Remember that terriers are intelligent and energetic—a bored dog will invent his own entertainment, often destructively. Ensure he's getting at least 30 minutes of vigorous exercise daily, plus mental stimulation through training or food puzzles. A tired terrier is much less likely to harass household plants. With time and consistency, he'll learn that ignoring greenery earns him better rewards than any illicit nibble could provide.
