14.Sugary food and drinks
Dogs may get sugar high that can cause a dog to be hyper and unfocused. They can also suffer a sugar low after a high causing dog to become sleepy, moody, lethargic and irritable. Too much sugar can lead to obesity, dental problems and possibly the onset of diabetes.
15. Corn on the cob
This is a sure way to get your dog’s intestine blocked. Corn is digested but the cob gets lodged in the small intestine. If not immediately removed surgically, it can be fatal to your dog. Too much corn kernels can upset the digestive tract as well.
