How to get my large dogs to eat dry kibble without adding treats?

Picky dogs can be so frustrating! I personally am not a fan of grain free diets. The truth is, they are a marketing fad. The reality is that only 5% of dog allergies are caused by food, and of that 5%, the majority is protein related. Grain allergies are extremely rare, and I never recommend feeding a grain free food unless the dog has a proven food allergy to grains. Grains are beneficial to dogs, as it helps fill them up and keeps them satisfied for longer. I recommend switching them to a brand such as Royal Canin, Hill's Science Diet, Purina ProPlan, or Iams. Whether or not you make the switch of foods, it's time to get tough with them if you want them to eat only dry dog food. They won't starve themselves, they will eat it eventually. You just have to be strong and not give in. Start by putting their food down in the morning for 15-20 minutes, taking it away after this time period even if they haven't eaten. Then no more food until dinner time. This is extremely important, they have to learn they need to eat the dog food or they don't get anything else. At dinner time, again put their food down for 15-20 minutes, taking it away after that time even if they haven't eaten. No more food until their dog food the next morning. Do not give in to them, no meat, cheese, or raw egg on their food. They will get hungry enough to eat the dog food only as long as you stay strong. Good luck, I hope this helps!

Although pictures can be deceiving,they do not seem to be underweight, ribs or spine are not visible. Dogs generally will not starve themselves unless unwell and 5-7days of fasting is generally accepted as safe. I recommend offering food for 20mibs, 4times a day initially but variety is your enemy here. I recommend choosing a high quality, tasty complete formula and use this for training treats also

Having a good source of a special treat like chicken is a blessing and a curse! IT sounds like he's learned that he can hold out for the food stuff. I would recommend very intentionally, slowly increasing the amount of kibble while decreasing the amount of chicken over about 2 weeks. Wetting and warming the dry food can make it more appetizing to him as well. Make sure to shred/cut the chicken as small as possible to mix with the food. Additionally, put the food down for 15 minutes, then pick it up and offer again later (2-4 times a day). If you wet and warm the food, just throw it away and start over each time. Also for a healthy, adult dog, it's ok if he goes a day or two without eating while you're transitioning. Good luck!

Mix a teaspoon or two of canned food in with the kibble. Leave it down for 20-30 minutes before picking it up whether they have eaten or not. Repeat this at the next mealtime. Do not offer any food between meals. Be consistent, dogs thrive on routine. Be firm, they will not starve.

It definitely seems like Benji likes his soft food, so it's going to take some time to get him transitioned to the dry food. The good thing is that dogs don't tend to not be finicky for too long before they give up and just eat what's available. It may take a few times of him missing a meal though. I think that is where most owners get concerned, because they feel like they are starving/torturing their dog. My opinion is that it's totally fine for them to miss a meal or two if you're giving them a food that's better for them. It is definitely not harmful for them, because it will take a long time (many days) before he would actually starve. I think the chicken broth idea is great! It may take a couple of weeks, but maybe you could continue wetting it with the broth and reduce the wetness gradually. Food allergies to grains is exceedingly rare, so you may double-check that this was diagnosed by a veterinarian. Usually, the owner gets some bad advice from the pet store employee, or reads some bad info on the internet and that's why they get the grain-free food. If that's the case, then this could open up some more options for feeding dry food. Dry food is better for dogs that tend to have bad teeth, because it does not build-up on the teeth as much. If you brush Benji's teeth regularly, then there is not as much need for the dry food; so you may consider that if all else fails. I hope that helps.

Tua likely prefers the treats and other food over the dry food. I recommend reducing the bones/meats/treats during the day to get him to eat his dry food. This is to ensure he's getting balanced minerals and vitamins as treats are not meant for maintenance food for dogs unlike formulated dry food.

It sounds like you have a couple of picky eaters on your hands! You could still try another flavor of kibble - Purina makes a ProPlan with some softer pieces or you could try Royal Canin or Hills. You may need to ‘wait them out’ and leave the dry kibble out until they eat it without offering anything new. It also won’t hurt to continue to mix a little wet food in if you aren’t opposed to it. Good luck!
