Our vegan, additive-free vitamin B complex contributes to maintaining balanced vitamin B levels and promotes normal nervous system function. This can be particularly beneficial during times of increased need.

Vitamin B plays a role in normal signal transmission between nerves and muscles, which is important for mobility and coordination. It also contributes to normal cognitive function.

The B complex can provide a valuable supplement for dogs in special situations, such as before stressful events or during periods of increased nervous strain. It promotes general vitality and strengthens the organism. It also contributes to physiological bladder function, normal back function, and nerve-muscle interaction.

Capsule shell cellulose

The feeding recommendation for DOG FIT by PreThis® Vitamin B Complex is as follows:

• For dogs up to 1.5 kg body weight: one capsule every 2 days
• For dogs from 1.5 kg body weight:
  • small: 1 capsule daily
  • medium: 1 capsule daily
  • large: 1 capsule daily
• For dogs over 50 kg body weight: 2 capsules daily

It is recommended to feed the capsule directly. If the dog does not accept the capsule, it can be opened and the contents sprinkled into the food or fed in a treat. 

DOG FIT by PreThis® Vitamin B Complex should be stored out of the reach of children, in a dry place and protected from light, as B vitamins are sensitive to light.

Our products should be fed once a day. It does not matter whether this is in the morning or evening, together or separately. However, it is important to follow the dosage recommendation and give the product regularly.

DOG FIT by PreThis® VITAMIN B is dosed to provide a balanced supplement to a dog's daily needs – tailored to their body weight (small, medium, or large).

The B vitamins contained are predominantly water-soluble vitamins. This means that excess amounts are generally not stored in the body but are excreted in the urine. This is especially true for vitamins B1, B2, B3, B5, B6, B7 (biotin), and B9 (folic acid).

Vitamin B12 is an exception: It is stored in small amounts in the liver and is particularly important in animal nutrition for the normal function of the nervous system and cell division. Here, too, the amount contained in the product is tailored to meet daily feeding needs, avoiding oversupply.

Important:
Use only according to the recommended dosage. Long-term, significantly excessive dosage—especially when combined with other products or feed additives—should be avoided, as even water-soluble vitamins can be stressful if they are continuously oversupplied (e.g., very high doses of vitamin B6).

If in doubt or in the presence of underlying health conditions, consultation with a veterinarian is recommended, especially in cases of pre-existing liver or kidney disease, which may alter excretion.

The onset of effect depends on the type and severity of the underlying disease. It usually takes at least 6 weeks before the first positive effects can be noticed, possibly a little longer. Please be patient, as natural products need time to take effect.

One bag contains 60 capsules and is sufficient for up to 2 months or longer, depending on the weight of the dog. It is similar with powder products, please refer to the product under contents and dosage.

We generally recommend long-term feeding for most DOG FIT by PreThis® products, especially for dogs with special needs or in advanced age. Continuous supplementation with micronutrients can make an important contribution to supporting the normal function of the musculoskeletal system and nervous system – especially in dogs with increased stress or age-related changes.

Exception: VITAL gastro

For short-term challenges such as temporary soft or watery stools, we recommend initially supplementing with VITAL gastro for about 5 days. The feeding recommendation is based exclusively on the acute phase.

Yes, the manufacture of our products is certified in accordance with HACCP ISO 9001 and therefore complies with the highest German guidelines.

Our products are free from undesirable additives, including genetic engineering, animal testing, gluten, fructose, yeast, soya, palm oil, flavourings, sugar, cereals and preservatives. They therefore fulfil the highest requirements for very good feed supplements.

By dividing the food into small, medium and large sizes, dogs can be given the right amount of nutrients to ensure optimal utilization. This prevents dogs from getting either too little or too much of certain nutrients, which can potentially lead to deficiencies or overdoses. A needs-based dosage is important for the health and well-being of the dog.

High-dose food supplements can be pointless in certain circumstances. On the one hand, they can be superfluous in a balanced and healthy diet, as the dog already receives all the necessary nutrients from the food. On the other hand, excessive doses of certain nutrients can even be harmful to the dog.

Another important factor is that the effect of high-dose food supplements has not been scientifically proven and is often only based on advertising claims and the subjective experiences of owners.

For hygienic reasons, the capsules should preferably be mixed in with the food or hidden in a treat. However, if the dog does not want to or cannot swallow them, the capsule can be pulled apart so that the contents can be mixed into the food or given together with some yoghurt, cottage cheese or liver sausage. As the capsules often consist of additional collagen, we recommend soaking them in water and mixing them into the food, especially with our joint preparations.

Our range includes pet food supplements.

They are not intended to cure diseases and do not replace a visit to the vet. Pet food supplements are not a substitute for a balanced and species-appropriate diet. They should be stored out of the reach of children, in a cool, dry place and protected from light. The recommended daily intake of supplementary pet food should not be exceeded.

Pre-existing conditions

If your pet already suffers from organic diseases, autoimmune disorders, intolerances, allergies, epilepsy etc. and may also be taking medication due to an illness, it is important to consult your vet before giving your pet supplementary foods. Our advice does not relate to the use of medications and their side effects or interactions. Please also consult the vet who prescribed the medication.

Important to know!

It is important to realise that natural pet foods often need to be given several weeks, and sometimes even longer, before a noticeable effect is seen. As with most natural products, this requires patience and perseverance. It is unlikely that you will notice an immediate effect within a few days or weeks. However, it is important to consider the use of pet supplements in combination with a healthy diet and lifestyle to achieve long-term results.

Painkillers - Please note!

It is important to consult your vet before administering painkillers. Unauthorised administration of painkillers such as aspirin, paracetamol or ibuprofen can have toxic effects in dogs and should be avoided. An overdose or improper use can have serious consequences and jeopardise your dog's health. Please contact your vet to determine the correct painkiller and dosage for your dog.

Interactions

If your dog is receiving medication from the vet for a medical condition and you are wondering if there are possible interactions with our products, it is important to note that this depends on the specific medication. Some chemical medications can have strong side effects, which makes a difference to possible interactions. First and foremost, interactions occur with chemical medications and are rare in combination with natural products, but cannot be completely ruled out. It is therefore advisable to always consult your vet before giving your pet supplementary foods.

Feed supplements are available as capsules or tablets. The capsules have clear advantages:

Gelantine capsules consist of additional collagen and cellulose capsules are an additional dietary fibre. We use a vegan rice extract as a filler, which is not possible with tablets, which is why many other manufacturers use magnesium stearate, for example. Furthermore, an exact dosage is guaranteed by the precisely defined amount of active ingredient contained;

The capsules are preferably fed hidden in a treat or mixed in with the food. If the dog does not accept the capsule, it can simply be opened and the contents mixed into the food.
