Dog Scratching and Not Eating

When a dog scratches and simultaneously refuses to eat, the two signs may be related through pain, nausea, or a systemic condition that affects both the skin and appetite.

Quick Answer

A dog that scratches and will not eat may be experiencing pain from an inflamed or infected skin condition, nausea associated with a systemic allergic reaction, or an unrelated illness that is affecting both systems. Because a dog that refuses food for more than 24 hours can become at risk for nutritional and metabolic concerns, veterinary evaluation is recommended when scratching and food refusal occur together.

What Can This Combination Look Like?

Appetite Changes to Watch For

Food refusal in dogs can range from mild disinterest to a complete refusal to eat. Owners may notice:

Reluctance to approach the food bowl, even when favorite treats are offered.
Sniffing food and walking away, which may indicate nausea rather than simple disinterest.
Drooling or lip-smacking, which are common signs of nausea in dogs.
Eating grass or non-food items, which can sometimes indicate gastrointestinal discomfort.
Partial eating where the dog eats a small amount and then stops, or shows interest only in very specific, strong-smelling foods.

Scratching Behavior in This Context

When scratching is accompanied by food refusal, the scratching may reflect:

Pain-related scratching, where the dog is responding to sore, inflamed, or infected skin rather than simple itchiness.
Anxiety-related scratching, where the dog's discomfort from not feeling well leads to compulsive grooming or scratching as a coping behavior.
Focused scratching on a specific area, such as the ears, paws, or a visible wound or hot spot, suggesting a localized problem that is causing significant discomfort.

What May Be Associated With This Symptom?

Painful Skin Conditions

Skin conditions that cause significant pain can lead to reduced appetite. Dogs in pain may be reluctant to eat because:

Hot spots (acute moist dermatitis) are localized areas of inflamed, infected skin that can be very painful. A dog with a hot spot may scratch intensely and avoid eating due to the discomfort.
Deep skin infections such as bacterial pyoderma or severe yeast infections can cause widespread pain, especially if the infection involves the muzzle, lips, or throat area where eating may directly irritate affected tissue.
Ear infections that extend to the skin around the face and neck can cause pain during chewing or head movement associated with eating.
Burns, chemical irritants, or foreign bodies embedded in the skin (such as grass awns or thorns) can cause localized pain and scratching that leads to reduced appetite.

Nausea and Gastrointestinal Involvement

Sometimes the scratching and food refusal share a common underlying cause related to the gastrointestinal system:

Food allergies or adverse food reactions can cause both skin itchiness and gastrointestinal upset, including nausea that leads to food refusal. While chronic food allergies more commonly cause skin issues and soft stools, an acute reaction to a new ingredient can produce nausea and a refusal to eat.
Pancreatitis is inflammation of the pancreas that typically causes vomiting, abdominal pain, and loss of appetite. While not a primary cause of scratching, a dog with pancreatitis may also have pre-existing skin issues that become more noticeable when the dog is unwell.
Gastrointestinal obstruction from a foreign object can cause nausea, vomiting, and food refusal. If the dog was also scratching before the obstruction developed (due to an unrelated skin issue), the two signs may appear connected even if they are not directly related.

Systemic Illness

Several systemic conditions can affect both the skin and appetite:

Kidney disease can cause uremic pruritus (itching related to toxin buildup) and nausea that reduces appetite.
Liver disease can cause jaundice-associated itching, nausea, and food refusal.
Infectious diseases such as tick-borne illnesses or systemic bacterial infections can cause fever, lethargy, loss of appetite, and sometimes skin changes.
Immune-mediated conditions such as pemphigus or lupus can cause severe skin lesions and systemic signs including fever and appetite loss.

What Should the Pet Owner Monitor?

Owners should track these details to share with a veterinarian:

Duration of food refusal - How long has the dog gone without eating? Note whether the dog is refusing all food or only regular meals while still accepting treats.
Water intake - Is the dog drinking normally? A dog that refuses both food and water is at greater risk for dehydration.
Vomiting or diarrhea - Has the dog vomited or had loose stools? If so, how many times and what did the vomit or stool look like?
Skin inspection - Check for hot spots, infected areas, swelling, foreign objects, or any changes since the scratching started.
Behavior and energy level - Is the dog lethargic, hiding, restless, or otherwise behaving abnormally?
Recent changes - Consider any new foods, treats, medications, household products, or environmental changes introduced in the past few days.

What Can the Owner Safely Do Next?

Offer Appealing, Bland Foods

If the dog is refusing regular food but is not vomiting, offering small amounts of bland, easily digestible food may encourage eating. Plain boiled chicken (shredded, no skin or bones), plain cooked rice, or a small amount of plain yogurt can sometimes tempt a dog that is feeling unwell. Avoid offering fatty, spicy, or strongly flavored foods, as these can worsen gastrointestinal upset.

Ensure Access to Fresh Water

Keep fresh, clean water available at all times. Some dogs prefer cool water, and offering ice cubes can sometimes encourage hydration. If the dog has not drunk water for 12 hours or more, contact a veterinarian.

Examine the Skin Gently

With clean hands, gently part the dog's fur and inspect the skin for areas of redness, swelling, heat, odor, discharge, or foreign objects. Pay particular attention to the ears, between the toes, the armpits, and the groin. If you find a hot spot or infected area, avoid touching it excessively, as this can cause additional pain.

Prevent Further Self-Injury

If the scratching is intense and causing skin damage, a recovery collar or cone can prevent the dog from making the situation worse. This is especially important if the dog will be waiting to see a veterinarian.

Record Observations

Write down the timeline of events, including when the scratching started, when the dog last ate normally, and any other signs you have noticed. This information helps the veterinarian assess the situation more efficiently.

When to Contact a Veterinarian

Seek Prompt Veterinary Care If:

The dog has refused food and water for more than 24 hours (or more than 12 hours for small breeds or puppies).
The dog is vomiting in addition to scratching and not eating.
Signs of pain are evident, such as whimpering, guarding a specific body area, or a hunched posture.
The dog appears lethargic, weak, or disoriented.
Visible skin infection is present, with swelling, pus, foul odor, or rapidly spreading redness.
The dog's gums are pale, yellowish, or dry, which can indicate dehydration or systemic illness.

Schedule a Routine Appointment If:

The dog is eating less but not refusing food entirely, and there are no additional signs of illness.
Scratching is the primary concern and appetite is slightly reduced but the dog is otherwise active and alert.
The food refusal may be related to a known issue (such as a recent vaccination or medication change) that the veterinarian is already managing.

Frequently Asked Questions

Could my dog just be too distracted by itching to eat?

It is possible. A dog that is intensely itchy may be more focused on scratching than eating, particularly if the skin discomfort is severe. However, if the dog has not eaten for more than 24 hours, other factors such as pain or nausea should be considered, and veterinary advice should be sought.

My dog is scratching and not eating but still drinking water. Is this less urgent?

Maintaining water intake is a positive sign, but persistent food refusal combined with scratching still warrants attention. If the situation does not improve within 24 hours or if additional signs develop, a veterinary evaluation is recommended.

Can stress cause a dog to scratch and stop eating?

Stress can contribute to both behaviors. A major change in the household (moving, new pet, schedule change) can cause stress-related reduced appetite and compulsive scratching or licking. However, before attributing the signs to stress, it is important to rule out medical causes through a veterinary examination.

What should I do if my dog has a hot spot and is not eating?

A hot spot that is causing enough discomfort to reduce the dog's appetite should be evaluated by a veterinarian. In the meantime, preventing the dog from further irritating the area (using a cone) and offering bland food may help. Hot spots can progress quickly, so prompt attention is beneficial.
