Avoid human food to your dog
1. Milk is good for dogs.
Maybe it is good, but milk has its own set of problems when fed to an adult dog. When a dog is young it has enzymes in her stomach to digest milk but as the dog grows up that enzyme is no longer there, so an adult dog cannot digest milk. it just goes in and comes out as such.only benefit it serves in an adult dog is that milk serves as a good laxative. Milk produces gas in the stomach causing the dog to pass foul-smelling gases. Your dog may suffer from loose motion or may even vomit. In some dogs, worm load becomes high due to milk. but this is not a general case. Some dogs may tolerate milk very well all through their life. you may get a clear picture by watching this following video
2. Feeding Dogs some edible items that are very tasty for humans but dangerous for dogs.
Pet owners especially children tend to give chocolate, cake or human biscuit, fried food to their pet as treat to show their love. These human food are dangerous for dogs as they cause kidney failure or poisoning. This tasty food should be avoided or it may cost the life of the dog.
3. Feeding the dog something which pet shop have pressurized you
There are certain food items which pet shop keepers push to sell just because it gives them a large profit or margin. These are again very dangerous for dogs. The latest example is meat jerky, as veterinarian and scientist find out these meat jerky are poisonous for dogs.
4. The more the better
The dog keeps on begging you for food and you keep giving the food and then your dog becomes sick due to overeating. It is best to give a measured quantity of food in every meal.
