B
（2024·南昌二模）Can dogs eat watermelon? A good pet parent knows there is lots of human food that dogs can eat. 1. And when it comes to fruits and vegetables dogs can and can't eat, the answers aren't always clear.
We once asked some experts whether dogs can eat any fruit or not. “With some safety measures(计量), yes! Watermelon is perfectly safe to give to dogs. 2. It's also very low in sugar, so if your dog is trying to lose some weight, it's a good treat,” says Dr Tate.
3. “Sometimes seeds can cause a little tummy upset(反胃),” says Dr Hawkins. “And some dogs might eat the whole skin in one piece, and that's very harmful to their stomachs too.”
Although dogs can eat watermelon, eating too much watermelon can be a different story. “If they eat more watermelon than they should, they can get diarrhea(腹泻). 4. As a pet parent, you should know what is good for your dog,” says Dr Tate. He suggests no more than 2 to 3 cups for larger dogs, 1 to 2 cups for medium dogs and 1 cup for small dogs.
“In fact, different dogs respond(反应) to things differently. Even when dogs can eat fruits like watermelon and the others, keep in mind that any time you're giving your dog a food that's not their normal food, there can always be a risk of a little tummy upset,” says Dr Hawkins. 5.
A. That is bad for their health.
B. And also a lot of food dogs can't eat.
C. It can actually be a healthy treat for them.
D. And sometimes dogs eat too much watermelon.
E. There cannot be any sugar when eating watermelon.
F. But the fruit's hard seeds(籽) and skin can be dangerous.
G. So he suggests checking with your animal doctor about your dog before eating.
