These fleshy green fruits contain a fungicidal toxin called persin which could give your dog a digestive upset. However, it’s the large avocado stone that presents most danger because it could potentially block the gastrointestinal tract, leaving your dog requiring surgery.
Contrary to popular opinion, bones are bad for dogs. Not only can they potentially choke your dog, they can cause blockages in the gut, intestinal damage and chipped or broken teeth.
The smell of unbaked yeasty bread dough could attract your dog’s attention but it should always be kept out of reach. If eaten, the dough could expand dangerously in your dog’s stomach, and the fermented yeast could become toxic.
Chocolate and cocoa-based products contain a stimulating substance called theobromine which is extremely poisonous to dogs – the darker the chocolate, the greater the risk. Even a few ounces of chocolate could leave your dog with sickness, diarrhoea, dehydration, and high blood pressure, and the effect is potentially worse in small breeds. If your dog appears restless or agitated and you think chocolate poisoning could be the cause, contact your vet.
Any product with caffeine can have a similar effect on your dog to chocolate and could ultimately damage its heart. So, keep your coffee, teabags and fizzy drinks well away from inquisitive tongues.
