What is Not Eating Dry Food?

Every dog has his particular set of food preferences. Some dogs prefer only dry food, some want a mix of wet and dry, and some will only eat human grade food prepared for them at home. All of these are within the range of normal dog behavior. However, if your dog normally eats dry food, or kibble, as part of his regular diet, then you have cause for concern if he refuses dry food altogether. This could mean that a dog on an all-dry food diet stops eating altogether, or that a dog on a mixed wet-and-dry food diet refuses to eat any food that has kibble in it.

  • Dehydration
  • Nausea
  • Oral injuries
  • Tooth root abscess
  • Tongue cancer

Dry food requires greater digestive effort, and is also harder on the mouth. If dry food is too difficult for your dog to digest, because of either its low moisture content or the effort it takes to digest it, or if it hurts him to chew dry food, your dog may communicate through his refusal that dry food is not a viable option. Dehydration and nausea can often subside with some home care, so make sure your dog has a full bowl of clean water. If your dog refuses his normal ration of dry food for more than 2 or 3 days, then you should take him in for a veterinary examination. There may be more serious issues that cannot resolve on their own. Oral injuries, tooth root abscess, and tongue cancer are all very serious problems that require veterinary care.

Why Not Eating Dry Food Occurs in Dogs

Problems with dry food consumption may originate in three parts of your dog’s body. Your dog’s refusal to eat dry food can stem from a general systemic failure, in which the need for hydration drives your dog to seek moist food. Your dog may have difficulty digesting dry food. There can also be various problems within your dog’s mouth that make it painful for him to process hard food.

Dehydration

A dog’s lack of hydration affects his entire body. A dehydrated dog may have a dry nose, mouth, and gums, with sticky mucous membranes; he may be tired, dull, and weak, he may pant more than normal and have a fast rapid-fire breathing pattern, and will be generally operating at a low capacity. Dehydration simply means that your dog’s body is losing more water than it takes in, through panting, vomiting, or simply drinking less, possibly because of a deeper condition. This is more likely to occur in young, old, and nursing dogs, as well as small breeds. 

Nausea

If your dog is nauseous, he has an upset stomach. This can occur as a reaction to illnesses, such as parvo and gastroenteritis, or environmental causes, such as motion sickness, blockage of the intestines, or toxic exposure. Nausea is an equal-opportunity condition; dogs of any age, breed, or sex can experience nausea. 

Oral Conditions

Oral conditions can include tongue cancer, tooth root abscess, and various other oral injuries, such as lacerations, puncture wounds, and broken teeth. Tongue cancer, also known as squamous cell carcinoma, is most likely to occur in dogs between 6 and 10 years old, and the breeds Keeshond, Standard Schnauzer, Basset Hound, and Collie (Boxers actually suffer from tongue cancer less than most other breeds). While there may be a genetic cause to tongue cancer, this is not certain, and there are no other clear causes. Tooth root abscess, also known as apical abscess, is a pus formation under or around your dog’s tooth or teeth. It develops from an oral infection, which can result from bacterial skin infections and puncture wounds caused by bites, splinters, and wood. It is a particular kind of oral injury. Any dog can receive an oral injury from a foreign object that he takes into his mouth. Dogs like to chew many different things, and some of those things, like sticks, rocks, and other hard objects, can injure your dog’s soft oral tissues, sometimes even breaking a tooth. As teething puppies chew more often than adult dogs, this may make them more vulnerable to oral injuries.

What to do if your Dog is Not Eating Dry Food

While both are potentially dangerous, mild cases of dehydration and nausea can be treated at home with simple measures. A dehydrated dog needs to get fluids in his system; it is really that simple. The extent of his treatment depends on the extent to which your dog is dehydrated. If the dehydration is mild, just make sure your dog has access to clean water; he can then treat himself by drinking enough water. A more dehydrated dog, who has serious underlying medical causes, may need fluids administered through subcutaneous or intravenous infection, such as through an IV or with a bag of lactated ringer solution. Both are typically done at your veterinarian’s office, though with proper training, lactated ringer solution can be administered at home. 

A dog may become nauseous by ingesting any number of inappropriate substances, such as unclean water, poisonous plants, various environmental toxins, and bad food. Your dog may cure a brief case of nausea by himself, through vomiting up the offending substance. However, if the nausea continues for more than a few hours, your dog should be examined by a veterinarian. Various tests will be administered to determine the exact cause of your dog’s nausea. Depending on the cause, your dog may be treated by administration of IV fluids or medications, and may even have his stomach pumped. 

Tongue cancer is an extremely serious condition. Any operable tumors must be surgically removed; this may include removing portions of your dog’s tongue or jawbone, followed by chemotherapy or radiation. This must be done by a licensed veterinarian; tongue cancer is always serious. Tooth root abscess and other oral injuries, on the other hand, can be treated at home in less serious cases. You may try brushing your dog’s teeth with a child’s or a pet’s toothbrush, applying a compress to any oral wounds, and rinsing your dog’s mouth with salt water. Take care to dispose of any potentially dangerous chewable items, such as wood and other breakables. More serious oral injuries may require lancing and draining of the wound, or even surgery, followed by antibiotics.

Prevention of Not Eating Dry Food

Tongue cancer probably can not be prevented. However, most other causes of your dog’s avoidance of dry food can be prevented. To avoid dehydration becoming an issue, make sure that clean water is available to your dog at all times. Keep any toxins and breakable items that your dog might chew away from him to avoid nausea, tooth root abscess, and other kinds of oral injuries. To avoid the infectious diseases that may cause nausea, be very careful in allowing your dog to socialize with other dogs, and keep his vaccinations current.

Cost of Not Eating Dry Food

The average cost of treating dehydration is $400, while the cost of nausea treatment ranges between $50 and $1000, depending on the cause. It costs an average of $1200 to treat tooth root abscess, while tongue cancer, which is dangerous, complicated, and expensive, costs an average of $12,000 to treat.

Has Symptoms

No interest in dry food

Medication Used

none

My dog Trooper has been on dry dog food (TLC) since I brought him home from the rescue centre at 8 weeks old. He is now 9 months. Recently he was kenneled for 8 days. Since he came home has shown no interest in his normal food. He is full of life and will eat anything tossed or dropped (accidentally or not). No sure but suspect kennel operator has added water to his kibble. He will eat it if I add a liquid flavour (chicken broth etc.) and or cooked vegetables i.e. carrots, peas etc.
Any Idea how I could get him beck to eating dry. He always has a supply of fresh water available.

Sometimes dogs will wait for you to cave in if they are wanting something different like wet food or wet kibble, it is a case of waiting for Trooper to eat his kibble; you should put down Trooper’s kibble and leave it there, he may cry and may not touch it but if you are more persistent than him he will eat the kibble when he gets hungry enough. It is possible that Trooper has another issue like a dental disorder or an oral injury making it painful to eat dry kibble, but first try to leave the kibble until he eats it; also make sure that the kibble isn’t stale or spoilt.
