Can I Give My Dog Weetabix For Fibre?

A dog and three Weetabix
Can dogs eat Weetabix for extra fibre?

Fibre is an essential part of a dog’s diet, and it helps maintain the gastrointestinal system’s health. Most dogs get their fibre from their food, and perhaps your dog has gone off their food and is having trouble going to the toilet. Maybe your dog’s anal glands aren’t emptying after they go to the toilet. Perhaps your vet has informed you that your dog needs more fibre. Whatever the reasons are, let’s determine if you can provide your dog with fibre by severing Weetabix.

It would be best to not feed your dog Weetabix for fibre due to the added sugars, salt, wheat and gluten in them. It would help if you looked for a more suitable source to provide your dog with extra fibre without any health risks. 

The below can help you find a better-suited source of fibre

What’s in Weetabix cereals

Whole-grain wheat

Wheat comes from a type of grass, and it’s used in various foods, including alcohol, and it’s even used in dogs food. Although dogs can have wheat as part of their daily food allowance, they will be consuming more daily wheat allowance that’s needed by giving dogs Weetabix. Also, to be cautious, some dogs have wheat allergies just like us humans and can develop symptoms below. 

Wheat allergy Smptyons

  • Ear infections
  • Skin Irritation
  • Sickness
  • Diarrhoea


Per serving of two biscuits contains 1.6 grams of sugar. Too much sugar in a dog’s diet can lead to obesity, dental problems, and even diabetes—another reason you should not give your dog Weetabix.


Dogs need a certain amount of sodium in their diet. Salt should be calculated with their normal daily food amount. Adding extra salt to a dog’s diet can be fatal. Your dog could suffer from sickness, diarrhoea, depression, high temperature, thirst and even have seizures.

If you want to add fibre into a dogs diet, choosing Weekabix isn’t the way forward. Weekibix contains several other ingredients, not just fibre, so you’re better off just adding what you need in a powder, liquid, or tablet that you can add straight to on top of their everyday food. 

We know that your dog shouldn’t have Weetabix as a source of fibre. However, you are here, so that means your looking to increase your dog’s fibre. Dogs should get the amount of fibre they need from their well-balanced dog food. However, some dogs may need a little more from time to time.

Why your dog may need extra fibre

These are the common reasons your dog may need extra fibre in their diet, and fibre will help with the below. 

  • Constipation
  • Diarrhoea
  • Anal glands

What is fibre?

Fibre is a type of complex carbohydrate. It’s different from other starches in that it resists digestion in the small intestines. Typically, fibre is fermented in the large intestine, which means that it takes a lot longer to digest than simple carbohydrates.

Why do dogs need fibre?

Proper fibre intake is essential for a healthy digestive system. It promotes the growth of beneficial bacteria in your dog’s gut, which will improve bowel regularity and produce firm stools that are easy to pass. Fibre also helps create an acidic environment inside the intestine to prevent undesirable bacterial overgrowth.

Fibre helps your pup maintain a healthy balance in the gut, which regulates bowel movements and keeps the colon clean to avoid certain diseases such as diabetes, obesity, stomach upset and colitis. The fibre aids both diarrhoea or constipation

Other sources to get fibre

Other than changing your dog’s diet to having better quality food with better ingredients, you can also try the following:

  • Better quality daily dog food
  • High fibre daily dog food diet
  • Psyllium husk
  • StoolRite
  • Flaxseed for dogs
  • Chia seeds for dogs

Fibre powders, tablets, and liquids found here from amazon will be better using instead of Weetabix.

How much fibre should a dog have?

The amount of fibre a dog needs depends on its size, weight and breed. For example, some breeds are more prone to digestive problems than others due to their digesting food habits. Generally, you’ll want to look at each well-known brand’s packaging, which will have a recommended daily allowance for fibre as listed in the back panel. You can also consult a veterinarian.

Fibre supplements are necessary in many cases but should only ever be added after consulting the vet, who knows what dosage of fibre would work best based on age and health status.

What happens if a dog has too much fibre?

The fibre in large doses has the reverse effect; if given too much, it can lead to poor nutrition in dogs. The fibre can bind the minerals together, making them weaker, resulting in weight loss, sickness, diarrhoea, poor coat, and flatulence. You need to make sure you are providing your dog with the correct amount and introducing it slowly. By contacting your veterinarian, they can help you give your dog’s personal needs the right amount. The size, breed, weight of your dog will play a big part in the amount of fibre they should have.  

What happens if dogs don’t get enough fibre?

Constipation, diarrhoea and urgency of the toilet are all linked to fibre deficiency.

Does my dog need more fibre?

As with humans, the dietary fibre function for dogs is to maintain the gastrointestinal system’s health. While most dogs will get the recommended amount from their daily food, some dogs need a little extra, and it could be to bulk out their faeces so the anal glands can be expressed correctly by themselves when going to the toilet. It’s also best if your dog empties them naturally rather than manually if possible.

Anal glands symptoms:

  • Scooting bum on the floor to itch
  • Painful sounds when going to the toilet
  • Your dog will not sit on its bum
  • Your dog bum may look swollen and red
  • Excessive licking around the bum area
  • Excessive biting around the bum area

Fibre is good at fighting diseases

Fibre is beneficial for managing diabetes in dogs, regulating blood glucose levels and minimising fluctuations. Dog food containing slowly fermentable fibre can also help manage your dog’s weight or aid in weight loss. Fibre increases bulk and helps dogs feel full while consuming fewer calories.

Can I give my dog bran flakes for fibre?

Bran flakes are made up of other ingredients that will not offer any benefits for your dog. Please look into other sources to get fibre, specifically designed for dogs.


We now know that human cereals that are high in fibre aren’t good for dogs. If you want to increase your dog’s fibre intake, you should use a different method, as listed above. Before you give your dog extra fibre, you should check first with your veterinarian and check the amount you need to give. All in all, don’t feed your dog cereals.
