Human biscuits are commonly shared with dogs, especially during tea time or as a quick reward. Many dog parents assume that if a biscuit is safe for people, it must also be safe for dogs. In reality, human biscuits are not formulated for canine nutritional needs.
Some types of biscuits may be tolerated in small amounts. But others can cause immediate problems such as vomiting or diarrhoea, especially if they contain chocolate, caffeine, or artificial sweeteners.
Regular feeding of high-sugar, high-calorie biscuits can also contribute to weight gain and obesity, which increases the risk of health issues over time. Dogs with diabetes should not be given human biscuits.
This blog explains which human biscuits are generally good for dogs, which ingredients must be strictly avoided, how much is too much, and healthier alternatives that support your dog’s long-term well-being.
What You Need to Know About Dogs Eating Human Biscuits
Why Some Human Foods Are Safe for Dogs
Dogs can digest a variety of human foods, particularly simple carbohydrates and cooked grains. Ingredients like wheat, rice, and oats are commonly used in commercial dog foods. This is why certain plain biscuits may not cause immediate harm when given occasionally.
However, digestibility does not equal suitability. Human biscuits are designed for taste and shelf life, not canine health.
Risks of Unsafe Ingredients
Many biscuits contain ingredients that dogs cannot process safely, even in small amounts. If we feed biscuits regularly to dogs, it can lead to:
- Weight gain and obesity
- Digestive upset
- Pancreatitis
- Toxic reactions (in severe cases)
Understanding ingredients is far more critical than the biscuit brand itself. Dogs are also smaller than humans, so ingredients that seem harmless to us can be dangerous for them.

Which Human Biscuits Are Generally Safe for Dogs?
The following biscuits are not dog treats but may be given occasionally in small amounts. This is particularly true if they meet specific criteria: plain, low in sugar and salt, and free of toxic additives.
Plain Digestive Biscuits
Plain digestive biscuits without chocolate, raisins, or artificial sweeteners are among the safer options. They are mostly made from wheat flour and fibre.
Limitations: Often high in sugar and fat; dogs should eat these biscuits as an occasional treat.
Marie Biscuits
Marie biscuits are commonly fed to dogs, especially in India. They are relatively simple in composition and usually free from toxic ingredients.
Caution: High in refined carbohydrates and sugar; not suitable for daily feeding.
Oatmeal Biscuits
Biscuits made primarily from oats are easier to digest and provide some fibre.
Best choice: Unsweetened, plain oat biscuits without flavourings or chocolate chips.
Peanut Butter Biscuits
Some peanut butter-based biscuits may be safe only if they are xylitol-free.
Important: Always check labels carefully; xylitol is highly toxic to dogs.
Whole Wheat Biscuits
Whole wheat biscuits may be slightly better than refined flour options due to higher fibre content.
Not suitable for: Dogs with wheat allergies or sensitive digestion.
Rice Biscuits
Rice-based biscuits are often gentler on the stomach and may suit dogs with mild digestive sensitivity.
Still a treat: Nutritionally incomplete and calorie-dense.
Homemade Biscuits
Homemade dog-friendly biscuits made with safe ingredients (oats, rice flour, pumpkin, eggs) are the safest option among “human-style” biscuits.
Advantage: Full control over ingredients, salt, and sugar levels.
Ingredients in Biscuits That Are Harmful to Dogs
Certain ingredients make biscuits unsafe regardless of quantity.
Chocolate
Chocolate contains theobromine (a bitter-tasting compound), which dogs cannot metabolise efficiently. Even small amounts can cause:
- Vomiting and diarrhoea
- Rapid heart rate
- Seizures
- Potentially fatal toxicity
Dark chocolate and baking chocolate are especially dangerous because they contain much higher theobromine levels than milk chocolate.
Xylitol (Artificial Sweeteners)
Xylitol is highly toxic to dogs. Even a small amount can cause:
- Sudden insulin release
- Severe hypoglycemia
- Liver failure
Xylitol is commonly found in sugar-free biscuits, cookies, and baked snacks. Always avoid products labelled “sugar-free” or “no added sugar.”
Raisins and Grapes
Raisins and grapes can cause kidney failure in dogs. The exact toxic amount is unknown, so any exposure is unsafe.
Onion or Garlic Powder
Often used to flavour savoury biscuits. These can damage red blood cells, leading to anaemia.
Powdered forms are more concentrated than fresh onion or garlic. They increase the risk of toxicity even in small amounts.
Excess Salt or Sugar
High salt may cause:
- Dehydration
- Vomiting
- Electrolyte imbalance
High sugar contributes to:
- Obesity
- Dental disease and cavities
- Increased risk of diabetes
- Energy spikes followed by crashes
How Much Biscuit Can I Give My Dog?
Here are some general guidelines about dogs eating biscuits:
- Treats (including biscuits) should make up no more than 10% of daily calories
- Biscuits for small dogs: this may mean one small piece
- Biscuits for medium dogs, half a biscuit occasionally is enough
- Biscuits for large dogs, one biscuit broken into pieces is often more than enough
Biscuits should never replace meals or be used as frequent snacks.
Not sure about the right treat quantity for your dog? Schedule dog diagnostic tests near you to assess overall health and nutrition needs.
Important Considerations When Feeding Biscuits to Dogs
Before feeding any biscuit to the dog:
- Read the ingredient list carefully
- Avoid flavoured, filled, or cream biscuits
- Do not feed daily or routinely
- Avoid biscuits in dogs with obesity, diabetes, pancreatitis, or food allergies.
- Keep biscuits out of reach to prevent accidental overeating
- Avoid feeding biscuits during training in excess, as repeated small rewards add up quickly
Always observe your dog after introducing any new food. If your dog has diarrhoea, vomits, itches, or is lethargic after eating a biscuit, discontinue feeding immediately.
The Connection Between Feeding and Bonding
Sharing food is often a way humans express affection. While dogs do associate treats with positive interactions, bonding does not require human biscuits. However, bonding does not depend on human food alone.
Healthier ways to bond include:
- Using dog-specific treats
- Verbal praise
- Interactive play
- Training sessions with low-calorie rewards
- Physical affection and routine engagement
Using food wisely helps build trust without harming your dog’s health. Your dog values attention and consistency more than table snacks.

Conclusion
Dogs can eat biscuits in minimal amounts. But they are not always healthy or necessary for dogs. Many contain sugar, salt, or hidden toxic ingredients that can cause long-term harm. When in doubt, choose dog-specific treats or homemade alternatives designed for canine health.
Frequently Asked Questions: About Feeding Biscuits to Dogs
Can puppies eat human biscuits?
Puppies should not be given human biscuits. Their digestive systems are sensitive, and poor nutrition can affect growth and development.
What should I do if my dog accidentally eats a chocolate biscuit?
Contact your veterinarian immediately. Chocolate toxicity depends on the type, amount, and size of the dog, and prompt care is critical.
Can I give Parle-G biscuits to stray dogs?
While commonly done, Parle-G biscuits are high in sugar and not nutritionally appropriate. If feeding strays, safer options include plain rice, eggs, or dog food when possible.
Are Oat Biscuits Better Than Plain Digestive Biscuits for Dogs?
Generally, yes, if unsweetened and unflavoured. This is because oats are easier to digest and contain more fibre.
How Often Can I Safely Give Biscuits to My Dog?
At most, once in a while, not daily. Biscuits should remain an occasional indulgence, not a habit.
