Raw meat

Food leavings (in large amounts)


can be hardly called a balanced food. They should never be over 10% of the whole amount of a dog's daily ration. Don't feed a dog with fatty meat and bones.


Fish (raw, boiled, canned)


If a dog is fed with fish in large amounts, it will surely lead to the loss of B vitamin and appetite. Excess of fish in a dog's ration causes agonies or even death (rarely). In addition, river fish sometimes contains parasites.

Plums and peaches


may lead to block of digesting system. They say, that peaches contain cyanide, that is harmful for both people and dogs.

Chocolate, coffee, tea and other caffeine-containing food


Products, containing theobromine, theophylline and caffeine, are quite possible to cause vomiting, diarrhea or be toxic for heart and nervous system.


Eggs (raw)


contain ferment avidin, reducing normal absorbing of B vitamin, that may cause hair and skin problems. By the way, salmonella, that sometimes lives in raw eggs, is dangerous not only for dogs?


So, have you remembered all the list of undesirable products for dog feeding? Of course, it is not as dangerous as it may seem and a piece of chocolate or a slice of orange will not cause serious damage to your dog. But try not to feed your dog with these products at all. I suppose, a dog will be more glad to eat a piece of meat instead of sweets.

We understand, that it will be not easy to ignore an asking eye expression of a dog, pretending as if it is not fed at all, when a dog sees that you are eating something from the list above. But try to keep yourself from giving it to a dog even rarely (some of them, for example, sweets) and some of them prepare a proper way (meat and eggs). Make a rule, do not feed a dog while you are eating. If you will give food to a dog from your table once, it will be asking for something every time you are eating. And it is not a good habit. Choose food for your dog carefully.
