DOG FIT by PreThis® CARE senior plus VITAMIN B
CARE nutrient supply for dogs of age.
For mobility, nerves, and vitality from approximately 7 years of age (depending on breed or mix).
Your dog has been with you for many years: loyal, happy, and with a very unique character. You may notice that your dog is slowing down a bit, his jumps are shorter, or he needs more frequent breaks. Many things change as a dog ages: metabolism, mobility, nerve strength, and even energy often decline. But age is not an illness, and you can do a lot to ensure your four-legged friend remains active, curious, and full of zest for life.
DOG FIT by PreThis® CARE senior and VITAMIN B complex. This is precisely why we developed our proven combination set, tailored for dogs from about 7 years of age (depending on breed and individual development). Our carefully selected micronutrients support age-related changes such as the normal function of joints, spine, nerve pathways, digestion, bladder function, cell protection, vision, and immune function. This way, you give your dog the chance to experience his senior years as alert, active, and happy as possible.
You can find the complete product descriptions in the individual products!
Strict specifications apply to CARE senior and VITAMIN B:
Certified production, free from genetic engineering, animal testing, magnesium stearate, gluten, lactose, fructose, yeast, soy, and unwanted additives, is a matter of course for us.
All-round support for a long, happy dog life
DOG FIT by PreThis® CARE senior was developed according to the latest scientific findings and is available in three sizes. CARE senior is a particularly high-quality supplement that we are particularly proud of.
For an all-round healthy life, not only an older dog needs a wealth of different nutrients. Unfortunately, these nutrients are not always present in sufficient quantities and bioavailability in common, mostly highly processed foods. Even with a high-quality, fresh diet, the aging body finds it increasingly difficult to metabolize the nutrients it needs in the intestines.
Furthermore, the natural aging process means that certain nutrients are increasingly needed to maintain all normal functions. In addition, metabolism and the intestinal ability to absorb nutrients can decline. This is also one reason why many older dogs lose weight.
For support, CARE senior contains vitamins A, E and D, the minerals iron and zinc, the joint, vertebral, intervertebral disc, cartilage and bone nutrients glucosamine, MSM, hyaluronic acid, collagen and calcium, as well as the valuable green-lipped mussel.
- Glucosamine, MSM, collagen & Hyaluronic acid: Supports cartilage, synovial fluid, intervertebral discs, ligaments, tendons, and fascia, so your dog stays flexible and enjoys exercise.
- Green-lipped mussel: Provides natural building blocks for synovial fluid, for greater mobility in everyday life.
- Calcium & Vitamin D: Support normal bone health and age-appropriate bone metabolism.
- Vitamin A: Supports normal vision and healthy mucous membranes.
- Vitamin E & Zinc: Contribute to cell protection and support normal skin and immune function.
- Iron: Supports oxygen supply, for more endurance and vitality in old age.
Vit B complex and Care Senior are tolerated really well !

DOG FIT by PreThis® VITAMIN B: The B vitamins are among the most important micronutrients for the dog's body. They are involved in numerous physiological processes, including energy metabolism, the normal function of nerves, psyche, heart, skin and mucous membranes, as well as the formation of red blood cells. They also contribute to reducing tiredness and fatigue and support general well-being, especially in older dogs or during special life phases.
An adequate supply of all eight B vitamins is particularly important in old age, as they are involved in the normal function of the nervous system and play a role in cellular metabolism. Our VITAMIN B complex is optimally tailored to the specific needs of dogs and is ideal as a daily supplement.
Many dog owners are unaware of the importance of the B vitamin group for their dog's organism.
DOG FIT by PreThis® VITAMIN B complex contains all eight essential B vitamins (B1, B2, B3, B5, B6, B7/Biotin, B9/Folic Acid, B12/Methylcobalamin).
For dogs up to 7 years old, please choose the combination JOINTS and VITAMIN B. For older and senior dogs, please choose CARE senior and VITAMIN B. If you are unsure, please ask us!
Your benefits at a glance: This is what our combination set can do for your dog:
- Provides your dog with targeted micronutrients for strong joints, a stable spine, and bones.
- Supports mobility, coordination, and cognitive function in old age.
- Supports the nervous system and natural impulse transmission.
- Contributes to age-appropriate bladder function and improved responsiveness.
- Can support digestion in old age.
- Contains vitamin A for clear vision and healthy mucous membranes.
- Provides powerful antioxidants such as vitamin E, plus zinc and iron, for cell protection and the immune system.
- Tailored to the age-related characteristics of dogs from approximately 7 years of age.
- Free from genetic engineering, artificial additives, gluten, fructose, soy, or yeast and lactose.

Vitamin B Complex
I'm very happy with the product—my 16.5-year-old dog […] is back in shape for her age. I'll order it again.

I'm thrilled
I'm thrilled! My 14-year-old dog has been taking both products for a while now, and we're getting along great with them. She seems more balanced overall, and I feel like they're also good for her coat and eyes. I'm very grateful and can wholeheartedly recommend both. Thank you so much!

Great—I highly recommend it!
I've tried a lot of supplements for my Goldi-Opi (almost 12 years old, with spondylosis), but so far I've never felt like anything really helped.

Great product
This combination has really done wonders for our 13-year-old dog—he seems like a different dog and is once again moving around the yard in a way that’s appropriate for his age and full of joy. The advice was excellent, even going beyond our questions—you rarely find that. We’re so happy!

Topp exceeded all expectations
I’ve been using this product for 2 months now and have already reordered it. I’m more than satisfied—ever since my 11-year-old dog started taking it, I feel like she’s doing much better. She’s no longer limping and gets up more easily in the morning. She’s been having age-related back problems, and getting up and walking had been difficult for her. But after just two weeks of taking the capsules, I noticed that she could move around much more easily again. She’s doing really well, and I highly recommend this product!

Recommended!
Not just a recommendation—I actually bought it based on a recommendation myself :-) My Labby, Moritz, is 12 years old (where has the time gone??), and I tried out the Care and Vitamin B Set. I feel like he’s become more active and has a greater zest for life—which makes me very happy. He’s also been peeing much less frequently. There’s nothing like honest recommendations from friends, and I wanted to share that with you. Götz with Moritz

Great for my dog
My little mixed-breed dog is 14 and has been noticeably declining lately—she’s often tired and, on some days, quite sluggish. She has osteoarthritis in her joints, and a lot of things just aren’t the same as they used to be. I’m very careful about her food and have a great nutritionist to help me. That’s how I came across DogFit. She’s been on the combo for two months now and seems much livelier—she moves better and has more energy again. There’s no such thing as a fountain of youth, but my whole family is so happy that she’s doing much better now!

DOG FIT by PreThis® CARE senior
- Dogs are fed 1 capsule small, medium or large daily. (morning or evening)
- Very light dogs, around 2 kg, are given 1 capsule small every 2nd day. (morning or evening)
- Dogs weighing 50 kg or more are given 2 capsules large daily. (1 x in the morning and 1 x in the evening)
The capsules are taken flexibly to optimally take the needs of dogs into account. It is ideal to mix the capsules in their closed form directly with the food or to hide them in a treat. This is the most hygienic and uncomplicated method.
If the dog has difficulty swallowing the capsules, they can be carefully opened to mix the contents directly into food or combine them with tasty treats such as yogurt, cottage cheese or liver sausage.
We recommend feeding the capsules, especially with joint preparations where the capsules consist of additional collagen. After the contents have been mixed into the food, they can be softened in a little water before mixing them into the food.
Store out of the reach of small children, cool, dry and protected from light.
DOG FIT by PreThis® VITAMIN B
- The preparation was developed according to needs and is optimally dosed up to 10 kg (small), 10 kg to 25 kg (medium) and from 25 kg (large) weight.
- Dogs receive one small, medium or large capsule daily, depending on their body weight.
- Very small dogs up to 1.5 kg body weight receive one small capsule every 2 days.
- Very large dogs with a body weight of 50 kg or more receive 2 large capsules daily.
Store out of the reach of small children, in a dry place and away from light, as B vitamins are sensitive to light.

Questions
Why this combination of CARE senior and VITAMIN B?
The two supplements work at different points and therefore complement each other well in daily feeding: CARE senior and VITAMIN B 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, CARE senior and VITAMIN B 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 CARE senior and VITAMIN B well tolerated?
CARE senior & VITAMIN B 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 CARE senior & VITAMIN B 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 CARE senior 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.
