If you feed him anything other than dog food, like scrambled egg, he's probably holding out on you. If you give him 'extras', always put them in his food bowl mixed with his food, never from the table and never separately.
If you want to get him out of the habit completely, you may have to add some egg to his food at each meal, gradually decreasing the amount each time till finally he will eat without the addition. You will have to blend it so he cannot just pick out the egg, without eating the food.
This can take as long as 1-2 weeks or more. Sometimes they start refusing and you'll have to add more egg in than you want to get them eating again... then start decreasing the amount again. You may even have to go to every other day, every third day... etc. until he stops looking for it. Good Luck! |
