The foods a Westie should never be given
A West Highland White Terrier should never eat chocolate, grapes, raisins, onions, garlic, chives, macadamia nuts, cooked bones, alcohol, caffeine, or foods sweetened with xylitol. Each one harms a dog in a different way: chocolate and caffeine overstimulate the heart and nervous system, grapes and raisins can damage the kidneys, and the onion family attacks red blood cells. Xylitol, found in sugar-free gum and some nut butters and baked goods, is dangerous in remarkably small amounts. Cooked bones are a different kind of hazard — they splinter as a Westie crunches them, and sharp fragments can injure the mouth, throat, or gut.
Why a small terrier's size raises the stakes
A Westie's size is what turns a dropped snack into an emergency, because the amount follows body weight. A single square of dark baking chocolate or a handful of raisins is a far bigger exposure for a dog of his build than for a large breed, and Westies are also famously prone to sensitive skin and touchy digestion. Rich, fatty human food — gravy, bacon, buttery scraps, cheese-heavy leftovers — may not be toxic in the strict sense, but it commonly triggers stomach upsets and skin flare-ups in this breed. Buttered corn cobs deserve a mention too: the cob itself cannot pass through a small dog's digestive tract and is a classic cause of blockage.
Where a Westie actually finds these foods
A Westie usually meets dangerous food through opportunity rather than an offered treat, because this is a bold, food-driven little hunter. The realistic risk points in a Westie household are the kitchen bin raided while you are out, grapes rolling off a counter he can reach by standing on a chair, a handbag holding sugar-free gum left on the floor, and well-meaning guests slipping him scraps at the table. Work through those routes one by one: a bin with a latched lid, fruit and baking chocolate stored in closed cupboards rather than on counters, handbags hung up, and a house rule that nobody feeds the dog from a plate, however hard he stares.
What to do if your Westie eats something on the list
If your Westie eats a food on this list, call your veterinarian straight away rather than waiting to see how he seems. Note what he ate, roughly how much, and when, and take the packaging with you if he is seen, because that information shapes what the vet decides to do. Signs that always warrant an urgent call include repeated vomiting, diarrhoea, drooling, restlessness or trembling, pale gums, weakness, or a swollen, painful belly. Do not try to make him sick at home unless a veterinarian specifically tells you to — with a small dog, acting on professional advice in the first hour matters far more than watching and hoping.
Making the rule stick with everyone in the house
The never-share list only protects a Westie if every person around him follows it, including children, visitors, and anyone who walks or feeds him while you are away. Say the rule out loud, keep a short written list on the fridge, and offer an approved alternative — a piece of carrot or a dog treat from his own jar — so people who want to spoil him still can, safely. In KinsLe, Care Teams lets you record that no-table-food rule as part of his care instructions, so family members and helpers all work from the same list and nobody guesses at the table.
