If you have to force feed your dog....maybe he hates it...maybe its not providing the proper nutrition...switch to a better quality dog food. You should not have to be force feeding your dog on a regular basis...there is something clearly wrong..maybe your dog has gastrointesinal problems and therefore eating is rough...switch to a high quality food and take your dog to a good vet to get checked out!
If your dog is picking out the boiled chicken and not really eating the kibble maybe consider cooking your dogs food, but be aware that boiled chicken alone is not a nutritionally balanced meal. I have put a good recipe below that I give my yorkie everyday.

Cesar has a 2.5% rating and considered a below average dog food on dogfoodadvisor. Its ingredients are questionable and do not look like it has much nutritional benefit. Educate yourself on good dog food nutrition and always read the ingredient label on every dog food you consider buying. Ingredients: Sufficient water for processing, beef by-products, liver, meat by-products, beef, chicken, chicken by-products, calcium carbonate, natural flavor, added color, sodium tripolyphosphate, carrageenan, dried yam, xanthan gum, potassium chloride, salt, erythorbic acid, natural filet mignon flavor, guar gum, zinc sulfate, vitamin A, D3, and E supplements, sodium nitrite (for color retention), d-calcium pantothenate, thiamine mononitrate (vitamin B1).

What dogfoodadvisor says: The first item in this dog food lists water, which adds nothing but moisture to this food. Water is a routine finding in most canned dog foods.
Three of the next six ingredients are all animal by-products, slaughterhouse waste. This is what’s left of slaughtered animals after all the prime cuts have been removed.
In a nutshell, animal by-products are the unsavory leftovers of processing considered by many “unfit for human consumption”.
In addition to organs (the nourishing part), this stuff can contain almost anything — feet, beaks, undeveloped eggs, heads, ovaries or developing fetuses — anything except quality skeletal muscle (real meat).
What’s worse, the ingredient labeled “meat by-products” is anonymous. It doesn’t even specify the source animal. So, this meat can come from almost anywhere, even diseased or dying livestock.
Although animal by-products can be high in protein, we do not consider ingredients like these quality items.
Now, returning to the list, the third ingredient is liver. Normally, liver can be considered a quality component. However, in this case, the source of the liver is not identified.
For this reason, it’s impossible to judge the quality of this item.
The fifth ingredient is beef. Beef is defined as “the clean flesh derived from slaughtered cattle” and includes skeletal muscle or the muscle tissues of the tongue, diaphragm, heart or esophagus.
The sixth ingredient is chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”. Beef and chicken are naturally rich in the ten essential amino acids required by a dog to sustain life.
From here, the list goes on to include a number of other items.
But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to have much of an effect on the overall rating of this product.
With three notable exceptions…
First, we’re always disappointed to find artificial coloring in any dog food. Coloring is used to make the product more appealing to you, not your dog. After all, do you really think your dog cares what color his kibble is?
Next, we note the inclusion here of we also note the presence of sodium nitrite, a controversial color preservative. Sodium nitrite has been linked to the production of cancer-causing substances (known as nitrosamines) when meats are exposed to high cooking temperatures.
Thirdly, carrageenan is a gelatin-like thickening agent extracted from seaweed. Although carrageenan has been used as a food additive for hundreds of years, there does appear to be some recent controversy regarding its long term biological safety.
And lastly, we find no detailed listing of the minerals included in this product. So, there’s no way for us to know with certainty if these minerals are chelated.
Non-chelated minerals are considered more difficult to absorb.
