can dogs eat custard

When it comes to our beloved dog’s, a balanced, nutritious diet forms an important part of their overall health and well-being. As pet owners, we often find ourselves questioning what foods are safe for us to share with our dogs. One such question that might arise is, “Can dogs eat custard?”

Custard is a creamy, delicious dessert enjoyed by many, but does it have the same appeal for our four-legged pals? In this comprehensive guide, we’ll delve into the world of custard, exploring what it is, its ingredients, and most importantly, whether it’s safe for dogs to indulge in this treat.

Can Dogs Eat Custard?

Let’s address the pressing question: “Can dogs eat custard?” directly. The answer is no, dogs should not eat custard. Custard often contains ingredients that can be harmful to dogs. While a small taste might not immediately lead to severe consequences, regular consumption or a larger quantity can pose risks to your dogs health, such as vomiting and diarrhoea.

Generally speaking, the ingredients in custard are not toxic to dogs. However, some custard recipes might include artificial flavorings, additives, and sweeteners like xylitol. Xylitol is especially hazardous for dogs and can cause a rapid drop in blood sugar levels that can lead to seizures, hypoglycemia, and liver damage.

In summary, it’s best to avoid feeding custard to your dog. It provides no nutritional value and often contains ingredients that don’t align with dogs’ digestive systems and nutritional needs.

What are the ingredients in custard?

Custard recipes generally consist of the following key ingredients:

1. Milk:

  • Role in Custard: Milk is a fundamental component of custard, contributing to its creamy and smooth texture. It also provides essential nutrients, including calcium and protein.
  • Concern for Dogs: Many dogs are lactose intolerant, meaning they lack sufficient levels of the enzyme lactase needed to digest lactose, the sugar found in milk. When lactose-intolerant dogs consume milk-based products like custard, it can lead to gastrointestinal issues such as diarrhea, vomiting, and gas.

2. Eggs:

  • Role in Custard: Eggs are crucial in custard as they act as a binding and thickening agent. The proteins in eggs coagulate during the cooking process, giving custard its characteristic texture.
  • Concern for Dogs: Eggs themselves are a valuable source of protein for dogs. However, some dogs may have allergies to eggs, which can manifest as skin problems, digestive disturbances, and other allergic reactions. Allergic reactions to eggs vary from dog to dog.

3. Sugar:

  • Role in Custard: Sugar is added to custard primarily for sweetening and flavor enhancement.
  • Concern for Dogs: High sugar intake is not part of a dog’s natural diet and can have adverse effects on their health. Regular consumption of sugary foods like custard can contribute to obesity, dental issues, and an increased risk of diabetes over time.

4. Flavorings:

  • Role in Custard: Flavorings such as vanilla extract are often added to custard to give it its distinctive taste.
  • Concern for Dogs: Natural flavorings like vanilla are generally safe for dogs when consumed in moderation. However, artificial flavorings and additives found in some custard varieties may not be ideal for canine consumption.

5. Thickening Agents:

  • Role in Custard: In some custard recipes, thickening agents like cornstarch may be used to achieve the desired consistency.
  • Concern for Dogs: Cornstarch itself is not toxic to dogs, but excessive consumption could lead to gastrointestinal discomfort. Dogs are generally better off without the added thickening agents often found in human desserts.

6. Artificial Sweeteners (Potential):

  • Role in Custard: Some custard products might contain artificial sweeteners like xylitol as a sugar substitute.
  • Concern for Dogs: Xylitol is highly toxic to dogs and can lead to hypoglycemia, seizures, and liver damage. It’s crucial to avoid custard or any food product sweetened with xylitol when sharing with dogs.

What are the Risks of Feeding Custard to Dogs?

Here are some reasons why custard is not suitable for dogs:

1. Lactose Intolerance

Many dogs are lactose intolerant, meaning they lack the enzyme required to properly digest lactose, the sugar found in milk. This can lead to digestive upset, including diarrhea, vomiting, and gas.

2. High Sugar Content

Custard contains sugar, which isn’t a part of a dog’s natural diet. High sugar intake can lead to obesity, dental issues, and an increased risk of diabetes.

3. Eggs and Allergies

While eggs are a good source of protein, some dogs may have allergies to them. Egg allergies can cause skin problems, digestive disturbances, and other allergic reactions.

4. Artificial Flavorings

Some custard varieties may contain artificial flavorings and additives that are not ideal for canine consumption.

5. Xylitol Concerns

In certain cases, custard might be sweetened with xylitol, a sugar substitute that is toxic to dogs and can lead to hypoglycemia and liver damage.

Common Symptoms in Dogs After Consuming Custard

If a dog consumes custard or custard-based treats, they may experience various symptoms and discomfort, especially if they have sensitivities to the ingredients found in custard. Here are common symptoms that dogs may exhibit after eating custard:

  1. Digestive Upset: One of the most common reactions is digestive upset, including symptoms such as diarrhea, vomiting, or excessive gas. Dogs may experience abdominal discomfort and may try to alleviate it by whimpering or pacing.
  2. Lethargy: After consuming custard, some dogs may become lethargic or unusually tired. This could be due to the body’s efforts to process the unfamiliar ingredients.
  3. Increased Thirst: The high sugar content in custard can lead to increased thirst and water consumption. Dogs may drink more water than usual to compensate for the sugar intake.
  4. Allergic Reactions: If a dog is allergic to any of the custard’s ingredients, they may display allergic reactions such as itching, hives, swelling, or skin irritations. Allergic reactions can vary in severity.
  5. Restlessness: Restlessness or agitation can be a response to discomfort caused by digestive upset or other adverse reactions to custard.
  6. Excessive Drooling: Some dogs may experience excessive drooling, especially if they find the taste or texture of custard unfamiliar or unpleasant.
  7. Changes in Bowel Movements: Custard can lead to changes in a dog’s bowel movements, including diarrhea or loose stools.
  8. Upset Stomach: Dogs may exhibit signs of an upset stomach, such as licking their lips repeatedly, gulping, or retching.
  9. Abdominal Pain: Dogs with digestive sensitivity to custard may experience abdominal pain or discomfort, which can lead to restlessness or seeking out unusual places to lie down.
  10. Behavioral Changes: In some cases, dogs may display behavioral changes such as anxiety or aggression, particularly if they are feeling unwell due to consuming custard.

My Dog Ate Custard – What Should I Do?

If your dog has consumed custard, it’s important to take appropriate steps to ensure their well-being. While custard may not be immediately life-threatening, it can lead to digestive issues, especially if your dog is lactose intolerant or has allergies. Here’s a step-by-step guide on what to do if your dog eats custard:

1. Assess the Situation

  • First, remain calm. Panicking won’t help your dog, and it’s important to think clearly.
  • Determine how much custard your dog has ingested and whether it contained any potentially harmful ingredients like xylitol or artificial flavorings.

2. Contact Your Veterinarian

  • If you suspect your dog has ingested a significant amount of custard, or if the custard contained harmful ingredients, contact your veterinarian immediately.
  • Provide as much information as possible about the custard, including the brand, ingredients, and the quantity your dog consumed.

3. Observe Your Dog

  • Monitor your dog closely for any signs of distress or adverse reactions. These could include vomiting, diarrhea, excessive gas, abdominal discomfort, or changes in behavior.
  • Note the onset and duration of any symptoms, as this information will be helpful for your veterinarian.

4. Prevent Further Consumption

  • Ensure your dog cannot access any more custard or other potentially harmful foods.
  • Secure garbage cans and keep tempting foods out of reach to prevent future incidents.

5. Offer Water

  • Provide your dog with access to fresh, clean water. This can help dilute the custard in their stomach and prevent dehydration.

6. Follow Veterinary Advice

  • If you’ve contacted your veterinarian, follow their guidance carefully. They may recommend bringing your dog in for an examination, inducing vomiting if necessary, or providing specific treatment based on your dog’s condition.

7. Observe for Allergic Reactions

  • If your dog has known allergies and the custard contained allergens like eggs, monitor closely for allergic reactions such as skin irritations, swelling, or difficulty breathing.

8. Maintain a Record

  • Keep a record of any symptoms and the timeline of events. This information will be valuable for your veterinarian’s assessment.

9. Avoid DIY Treatments

  • Do not attempt to induce vomiting or administer over-the-counter medications without consulting your veterinarian. The wrong treatment could potentially make the situation worse.

10. Prevention for the Future

  • Learn from the incident and take steps to prevent your dog from accessing unsafe foods or treats in the future.
  • Educate family members and anyone who cares for your dog about the importance of keeping harmful foods out of reach.

It goes without saying that your veterinarian is the best source of guidance in situations like this. They will assess your dog’s specific condition and provide tailored recommendations for their care. Early intervention and professional advice are crucial for ensuring your dog’s safety and well-being if they’ve consumed custard or any potentially harmful food.

Safe Alternatives to Custard for Dogs

If you’re looking to treat your dog to something special, consider these dog-friendly alternatives to custard:

  1. Plain Yogurt: Plain, unsweetened yogurt is a good source of probiotics and can be a healthier substitute for custard. Make sure the yogurt doesn’t contain any artificial sweeteners or additives.
  2. Frozen Fruit Treats: You can freeze small pieces of dog-safe fruits like blueberries or watermelon for a refreshing and nutritious treat.
  3. Commercial Dog Treats: There are numerous commercial dog treats available that are formulated to be safe and delicious for your pup.


In conclusion, the question “Can dogs eat custard?” should be approached with caution. While a small taste might not lead to immediate harm, custard’s ingredients, particularly its lactose, sugar, and potential allergens, make it an unsuitable choice for regular canine consumption.

As responsible pet owners, it’s essential to prioritize our dogs’ health and well-being by offering them treats specifically designed with their dietary needs in mind. When in doubt, always consult your veterinarian for advice on what foods are safe and appropriate for your furry companion. Remember, a happy and healthy pup is a well-loved pup.
