This is overall a nice picture, but here’s some elaboration.
Avocados only pose a mild toxic risk to dogs. Avocados contain persin, an antifungal toxin, that usually only causes mild digestive upset in dogs and cats. For dogs, the main danger of avocados is ingestion of the pit, which can cause intestinal blockage. Avocados are dangerously toxic to birds and large animals like cattle, goats, and horses.
Do I even need to explain why alcohol poisoning is bad. Which leads me to the next point.
Unrisen bread dough containing yeast can cause bloat, GDV (twisted stomach), and also alcohol poisoning. Yeast is a living organism that digests the sugar in the dough and ferments it, producing CO2 (which causes the rising) and, of course, alcohol.
Caffeine is highly dangerous to small animals like dogs and cats. Caffeine is a stimulant and ingestion of a sufficient amount can cause vomiting, seizures, and death.
Chocolate is dangerous for the same reason. The culprit is theobromine, a xanthine compound found naturally in the cacao plant and similar to caffeine, which is also a stimulant. The darker the chocolate, i.e. the higher the cocao content, the more dangerous it is. It’s even dangerous to humans in high enough doses.
Grapes, raisins, and anything containing natural grape juice can cause acute kidney failure in dogs, though the means and source of the toxicity is not fully understood.
Garlic and onions can cause red blood cells to rupture and result in lethargy, weakness, and gastric upset in dogs.
Macadamia nuts, like grapes, are toxic for a reason that is not fully understood. However, unlike grapes, ingestion of these nuts is rarely fatal, but can cause very uncomfortable symptoms to your dog such as tremors, lethargy, and an inability to walk until symptoms pass.
Salmon poisoning disease is fatal and can actually come from several species of fish. The danger does not lie in the meat of the animal itself, but the threat is posed when a fluke (flatworm) parasite of the fish itself has a hitchhiker. Rickettsia is a group of parasitic bacteria that infect the fluke, which in and of itself is usually harmless. Cook your fish!
Xylitol is highly dangerous. In humans, this artificial sweetener has no noticible effect on insulin production. However, in dogs, it causes a dangerous increase in insulin and can ultimately result in liver failure if not immediately attended to.
So yeah, the picture is nice, but now you know why these things are dangerous.
