Citrus Fruits (Lemons, Limes, Grapefruits, and Oranges)

Though citrus fruits are not that toxic to dogs, they can be very acidic and can cause digestive problems when eaten in large amounts. All citrus fruits have essential oils and chemical compounds that can be toxic to dogs especially if they have a sensitive digestive system.

For example, limes have high citric acid and sugar that can cause vomiting and diarrhea, while grapefruit can be safe for dogs except for its skin.

According to The American Society for the Prevention of Cruelty to Animals (ASPCA), the grapefruit plant and its peel are toxic to dogs. The flesh of the grapefruit is not that dangerous, but it can cause tummy irritation to dogs if a large amount is eaten.

The process of fruit dying like raisins, apricots, figs, and dates concentrates the sugar that makes it too sweet for dogs. Experts also found out that these fruits contain chemical compounds that can be harmful to dogs.

If eaten, your dogs can experience vomiting, diarrhea, or even dried-fruit poisoning that can cause kidney failure – but take note that these effects may vary depending on dog breeds and body size.
