Can Dogs Eat Tomatoes? Is It Toxic Or Non Toxic?


Dogs usually show a willingness to follow commands, but their love for you sometimes drives them closer to where you’re eating. Once by your dinner table, they might occasionally grab the chance to nibble on some of your preferred snacks, possibly raw tomatoes or items containing tomato.

Even to red tomatoes, the dog may be allergic to them, which may show as diarrhea, gastrointestinal distress, vomiting, skin rashes, or upset stomach. Another important thing to note here is if your dog has any problem with his kidneys or bladder, even the red tomatoes are not good for him, owing to being high in oxalates, which can create urinary stones.
