Common Reasons Your American Mastiff Won’t Eat

Ask A Vet Dog Won't Eat Dental Issues

1. Oral Health Issues and Oral Pain

Dental disease like periodontal disease, dental abscesses, and fractured teeth are very common in dogs and can cause severe oral pain that prevents them from wanting to chew their food. Signs that your American Mastiff has dental issues include bad breath, inflamed gums, pawing at the mouth, and dropping food. Dogs may start eating only soft food or refuse to eat their meals.

See your vet immediately if you notice these signs of dental disease, as untreated infections can spread bacteria to the circulatory system. Your vet will likely recommend a full dental cleaning and extraction of diseased teeth under anesthesia to relieve your dog’s oral pain. They may also prescribe antimicrobials and pain medication. With treatment, your American Mastiff appetite should bounce back within a few days once the mouth pain subsides.

Sick Dog Nausea from Gastrointestinal Upset

2. Nausea from Gastrointestinal Upset

When dogs experience nausea, vomiting, diarrhea, or other GI issues, eating is the last thing they want to do. Issues like dog food allergies, inflammatory bowel disease, pancreatitis, infections from parasites, and viral enteritis can cause GI disturbances, can be the cause an American Mastiff wont eat.

By conducting blood tests, analyzing fecal samples, and getting abdominal imaging, the primary reason for appetite loss can be detected. The appetite usually returns quickly after the nausea reduces, especially with treatments involving anti-nausea medications, antibiotics, anti-inflammatory drugs, and tailored diets.

Always stick to the treatment plan set out by your veterinarian and provide the advised dosages to your dog.

Scared Dog Anxiety and Stress Wont Eat

3. Anxiety and Stress

American Mastiffs are sensitive to changes in routine, travel, new environments, loud noises, and meeting unfamiliar dogs or people. Often, these situations filled with tension or anxiety result in a dog’s diminished appetite or total rejection of food.

To keep your dog’s anxiety at bay, stick to regular schedules as much as you can and opt for anti-anxiety treatments or supplements if the vet suggests. Also, stimulate their appetite by hand feeding delicious foods like cooked chicken, canned puppy food, or dry food such as kibble soaked in broth.

Once your American Mastiff begins to acclimate to the alterations causing anxiety, you’ll likely notice an uptick in their appetite.

Dog Wont Eat Due To Lack Of Smell

4. American Mastiff Decreased Sense of Smell

For elderly dogs and those with persistent nasal or respiratory ailments, a reduced sense of smell often becomes a challenge. If dog food seems bland or unappetizing, dogs simply aren’t motivated to eat it or have no want to eat.

Try warming up canned food or wet foods to release a stronger aroma.On their daily kibble, you might sprinkle richly scented toppings like chicken stock, cheese shreds, bacon fragments, or preserved fish.Such additions render the meal more attractive.

If an upper respiratory infection is causing the smell loss, antibiotics and nasal decongestants from your vet can help restore their appetite.

Dog Picky Eater Wont Eat

5. Picky Eating Habits

A handful of American Mastiffs inherently have selective eating habits, possibly because they’re tired of their regular food or have a liking for human dishes. It’s not uncommon for particular eaters to start bypassing meals or being very discerning with their food choices.

To satisfy a picky pup’s preferences, try regularly rotating between 3-4 different high-value foods like air-dried, raw, or wet foods. Consider enhancing their regular kibble with tempting additives such as chopped ham, whisked eggs, unsweetened yogurt, or cottage cheese.

It’s essential not to feed them human leftovers, so you don’t reinforce choosy behavior. Given enough patience and some inventive ideas, you can pinpoint the meals your fussy dog relishes.

We recommend trying these products for picky American Mastiffs.

6. Underlying Medical Issue

Many internal health challenges, not limited to dental and gastrointestinal conditions, can result in a lack of appetite in American Mastiffs. These include kidney disease, cancer, hypothyroidism, urinary tract infections, and organ failure.

Make an appointment with your vet right away if your adult dog goes 24+ hours without eating or seems lethargic. Diagnostic testing like bloodwork, urinalysis, and imaging will uncover if your dog has an underlying medical problem sabotaging their appetite.

Treatment of the condition often brings back normal hunger very quickly once your dog starts feeling better. However, neglecting to treat health problems poses risks.

Dogs

thrive on routines, and any disruption can often lead them to become finicky eaters. Scenarios where this occurs include switching food brands, feeding at different times, travel, boarding, guests in the home, moving houses, or a new family member like a baby or puppy.

Help your American Mastiff adjust to routine changes gradually over 2-3 weeks. Take the case of altering their diet: carry out the transition across 7-10 days, methodically adding more of the new food and reducing the old.

Consistency and predictability will help bring back their regular appetite.

On hot summer days, panting and trying to stay cool actually suppresses appetite signals in a dog’s brain. During the hotter months, ensure your dog always has access to shady spots, cold surfaces, and replenished water.

This helps encourage eating on those hot days.

Some American Mastiffs feel anxious eating around other pets and may refuse to eat as a result. Competing resources, especially when other dogs or cats are around—like food, toys, and human companionship—can create stress.

Consider feeding them in a different room and employing baby gates to alleviate the mealtime tension. Also, provide multiple food bowls spread widely apart to minimize competition. Adapting in this manner, most nervous eaters start feeling at ease with their meals again.
