Challenges for Spine & Nerves

DOG FIT DogThe dog's musculoskeletal system is a complex system. Age-related changes to the spine (like spondylosis), breed-specific challenges (like wedge vertebrae), strain on the intervertebral discs (discopathy), or issues like cauda equina syndrome place high demands on the nutrient balance. Targeted nutritional supplementation is essential here to support normal function.

The stiffening of the spine or pressure on the nerves can lead to irritation. As a result of nerve irritation, signal loss, incontinence, trembling (tremor), or coordination disorders can occur. Joint changes (arthrosis) can also develop due to an altered gait. Here, nutritional support can be a valuable accompaniment.

Vitamin B for Trembling (Tremor)

DOG FIT DogTrembling (tremor / head-bobbing etc.) often has a neurological background. Conditions like arthrosis and spondylosis, as well as age- or illness-related muscle weakness, can be contributing factors. A weakened or irritated nervous system always plays a large role in trembling. Supplementing with B vitamins can make an important contribution, as they are essential for the health of the nervous system.

Please note: To support regeneration after acute phases of increased strain, our combo set of VITAL regeneration and VITAMIN B is the preferred choice for comprehensive nutritional supplementation.

DOG FIT DogIf you notice typical signs of reduced nerve function in your dog, in addition to pain reactions or gait abnormalities, a veterinary diagnosis is essential. Alongside this, measures to strengthen the nerve cells can be useful.

A Vitamin B complex tailored to the needs of the dog's organism can effectively support normal nerve function. The micronutrients of the B-complex are essential for the normal function of nerve cells, as the dog cannot produce them itself.

Furthermore, it is important to provide nutritional support for the aging spine. It is also important to strengthen the intervertebral discs of the spine as well as the surrounding ligaments, tendons, and fasciae. Here too, micronutrients, also known as joint nutrients, are important for support.

Combo Product 1: JOINTS

DOG FIT DogJOINTS is available in three weight classes to allow for appropriate dosing for your dog. The certified feed supplement provides valuable micronutrients (incl. Devil's Claw & Frankincense), which are specially tailored to the needs of dogs. The combination of these micronutrients supports elastic and resilient cartilage tissue and promotes its regenerative capacity. Additionally, they strengthen the fascia, ligament, tendon, and vertebral soft tissue, and stimulate the production of joint fluid (synovial fluid).

Combo Product 2: VITAMIN B

DOG FIT DogThe nerve pathways run through the entire body. Irritation from spondylosis or a herniated disc can lead to pain and neurological deficits, such as paralysis, coordination disorders, or trembling (tremor).

For the nervous system to function smoothly, it requires a constant supply of the entire Vitamin B complex. Supplementation as a precaution can also provide nutritional support for the nerves. Even in demanding phases, the micronutrients significantly support normal nerve function.

The most important benefits of the micronutrients:

  • Proven combination to support the spine and back with special challenges.
  • Support for the normal function of vertebrae and joints.
  • Nutritional support for nerve function.
  • Support for normal nerve function in the limbs.
  • Support for secondary symptoms such as tremor (trembling) or coordination disorders.
  • Support for cartilage, synovial fluid, ligaments, tendons, and fasciae.
  • Support for the normal function of signal transmission within the nerve pathways.
  • Protection of cells from oxidative stress.
  • Support for normal energy metabolism.

My German Shepherd is more agile again

For about 40 days now, I've been giving my six-year-old German Shepherd […] these two capsules in his food in the morning and the vitamins in the afternoon as well. […] He's jumping around again and is generally more agile. I can recommend this combination.

Great products!

My English Bulldog, Gisela, is now 7 years old. Over the past year, after lying down for long periods, she’s often had a harder time getting back up to speed, and overall she’s been a bit more sensitive. Since I didn’t want to give her pain medication long-term, I decided to try the combination of Joints & Vitamin B. We’ve been giving her both products for about six months now, and I feel like she’s responding very well to them. Gisela seems more balanced and is keeping up better in her daily life. I’m convinced of their effectiveness and will happily continue using these products!

Very good!

We have a French Bulldog with disc and spinal problems. Ever since Rudi started getting the combination of Joints and Vitamin B, he’s been more mobile and better balanced again. A big thank you also to the customer service team—they’re always friendly and helpful! ❤️❤️

Thank you so much!!

I’d like to say thank you for the product combination! After Jack reacted to the meds from the vet and the homeopathic remedy didn’t work, I was at a loss at first. My veterinary physical therapist then recommended Dog Fit to us. Thank goodness! After just a few days, I could tell that Jack was feeling better!!

I really can't recommend it enough

I'd like to chime in, too. My 8-year-old dog has also benefited greatly from a combination of Vitamin B and Joints. Since then, she seems more agile and recovers better after playing fetch.

Very effective against spondylosis

Hello, dear team, My 14-year-old Jack Russell had been experiencing mild incontinence issues for quite some time; I noticed tremors from time to time, and he was getting slower and slower on walks. The vet then diagnosed him with spondylosis, which is common in dogs his age. The vet recommended that I give him pain medication long-term, but I didn’t want to do that. Luckily, while searching online, I discovered your website. I’ve been giving him a combination of Joints and Vitamin B for about 4 weeks now, and it’s really helping him! He hardly shakes anymore, his incontinence issues are almost gone, and he’s become much more active again :-) Many people have noticed the difference after just a short time, and I’ve happily recommended your products to others right away. Thank you so much!!!!

Very satisfied

Hello, dear team and readers of my review, These products were recommended to me by my animal naturopath. Thanks to this, along with physical therapy, we were fortunately able to avoid spinal disc surgery. My dog is clearly on the road to recovery. As for the store, I’d like to say: Deliveries are always fast, and the advice I received beforehand was knowledgeable and extremely friendly. For me, it’s a well-rounded package!

Thank you!

A BVS led to cauda equina syndrome in my dog. It's helping a lot—he's moving much better and has less pain. Thanks for the fast delivery. Best regards, Klaus

A really good remedy

I don't usually leave reviews, but I'm happy to do so this time. Both products are really helping our dog, Spondy; we're really happy. We've noticed a significant reduction in pain during flare-ups, and the tremors in his legs hardly ever occur anymore. It does take some time for it to take effect, though.

Questions

Why this combination of VITAMIN B and JOINTS?

The two supplements work at different points and therefore complement each other well in daily feeding: VITAMIN B and JOINTS can be given in one step instead of ordering two products separately. The set is also cheaper than buying individually. You will find what each supplement contains under “Ingredients”.

Give both together or split between morning and evening?

Both work. As a rule, VITAMIN B and JOINTS can be fed together or split between morning and evening. All that matters is that your dog receives each of the two once a day. Choose whatever fits your daily routine.

Are VITAMIN B and JOINTS well tolerated, are there any side effects?

VITAMIN B & JOINTS is generally very well tolerated. We select our ingredients for high quality and a natural composition. As with any natural product, an individual dog may still react sensitively to a single ingredient. If you notice signs of intolerance, pause the supplement and get in touch with us. We are happy to help. If your dog has pre-existing conditions or receives a special diet or medication, please also talk to your veterinary practice.

When can I expect to see first results?

Give VITAMIN B & JOINTS regularly for at least six weeks, in some cases longer. How quickly you notice something varies from dog to dog and depends on your dog's individual needs. Natural formulations need time to unfold their supporting properties: regular feeding matters more than a high single dose.

How long does the set last?

The set contains two packs of 60 capsules each. Feeding both supplements daily, it lasts around two months. If your dog receives an extra capsule according to the dosage recommendation, it will last correspondingly less.

My dog won't eat the capsule: what can I do?

That can almost always be solved. Many dogs accept the capsule more readily when it is embedded in something soft: a spoonful of wet food, quark or a piece of liver sausage usually does the trick. If your dog doesn't like the capsule at all, you can also open it and mix the contents into the food. One note on this: with JOINTS the capsule shell is made of high-quality beef gelatine and is therefore a valuable component in itself. So don't throw it away after opening. Soften it briefly in a little water and add it to the food. What matters most is regularity: an occasionally missed dose is no problem, but feeding should not be interrupted for long.
