6 – rotten food:
It may seem normal to throw a piece of food into your puppy, even if it is not. This can be a problem if the food is moldy, because some molds containing food contain toxins, which can cause tremors. Aggravate until it turns into convulsions, and the end result if you leave untreated dogs can die.
7. Corn:
Corn chunks may not seem hard to chew for your dog, but they can actually be deadly and corn kernels can cause intestinal obstruction with serious problems.
