Dogs should avoid certain fruits due to potential health risks. Grapes and raisins can cause kidney failure. Citrus fruits like oranges, lemons, and limes may lead to digestive issues. Avocado contains persin, which might upset a dog’s stomach. Cherries and their pits can pose risks, as the pits contain cyanide. Moreover, be cautious with fruits containing seeds or pits, as they might cause choking hazards or gastrointestinal blockages. Always consult your vet before introducing new fruits, as each dog’s tolerance can vary. In my experience, sticking to dog-friendly fruits like apples (without seeds), bananas, and blueberries is a safer choice for your furry friend’s health.
