Dogs shouldn't eat avocado. Dog owners should not feed dogs avocado, even though it's nutritious. Avocado pits, skin, and leaves contain persin, a toxin that makes dogs vomit and diarrhea.
Although avocado flesh has less persin than the rest of the plant, dogs might still be overwhelmed by it. Avocado flesh is heavy in fat, which can irritate dogs' stomachs or induce pancreatitis if eaten in excess.
Dogs should not eat cherries. Cherry trees are deadly to dogs because they contain cyanide, save for the seed meat. Cyanide impairs cellular oxygen transfer, denying your dog's blood cells oxygen.
Grapes should never be fed to dogs. If you think your dog ate grapes, call the vet. Grapes and raisins are hazardous to dogs of all breeds, sexes, and ages. Grapes are so poisonous they can cause abrupt renal failure.
No, dogs shouldn't eat tomatoes. While dogs can eat ripe tomato flesh, solanine in the plant's greens is hazardous. As a precaution, avoid tomatoes altogether. A dog would need to eat a lot to get sick.
Citrus fruits like lemons, limes, and grapefruits can make a dog sick to their stomach, despite the fact that they are not harmful to dogs.
