Recovery course for older dogs » valuable supplement for senior dogs
Your dog's needs change over the years. This is exactly where DOG FIT by PreThis® CARE senior comes in for dogs from around 7 years of age. It supplements daily feeding with a high-quality combination of selected and age-appropriate micronutrients to help older dogs stay active and vital – day after day.
This formula supports the normal function of cells, eyes, musculoskeletal system, bones, teeth, immune system, and age-appropriate metabolism. It also provides support during weight loss and muscle atrophy. For optimal care during your dog's prime years.

With increasing age, a dog's metabolism and nutrient requirements change. Often, the usual food can no longer be utilized as efficiently, which can lead to unwanted weight loss or muscle degradation. The DOG FIT by PreThis® CARE senior formula also contributes to maintaining the normal function of joints, cartilage, intervertebral discs, bones, and the entire musculoskeletal system - an important prerequisite for remaining active and maintaining muscle mass.
CARE senior also accompanies physiological processes that are more demanded in old age: It supports normal cell function, helps protect cells from oxidative stress, promotes normal blood formation, and provides nutrients for skin, coat, eyes, immune system, and energy metabolism.

DOG FIT by PreThis® CARE senior combines, among others, MSM, collagen, glucosamine, calcium, hyaluronic acid, green-lipped mussel, iron, zinc, vitamin A, vitamin D and the antioxidant vitamin E.
As with many of our products, strict quality standards also apply to CARE senior:
Certified manufacturing, free from genetic engineering, animal testing, magnesium stearate, gluten, lactose, fructose, grains, sugar, and preservatives, as well as the use of ingredients in feed quality are a matter of course for us. This way, we ensure that older dogs receive high-quality micronutrients in absolute purity and with the best bioavailability with CARE senior .
I've been using this product for two months now and have already reordered. I'm very satisfied because since my 11-year-old dog started using it, she seems more mobile overall and starts her day more easily in the morning. Due to her age, she was somewhat limited before, but after a short time, she showed significantly more enjoyment in exercise again. I highly recommend it.

Thanks to its versatile formula, DOG FIT by PreThis® CARE senior is suitable for many areas of application: It supports the dog in special phases of stress, contributes to a balanced supply for the entire organism, and supplements the diet with regard to age-related changes. As soon as you notice that your dog is getting older (depending on the breed from about 7 years), we recommend early, accompanying supplementation so that he can experience the time of aging vitally and actively.

Everything's great
My dog, a large breed weighing 38 kg, is now 8.5 years old. She’s on the Senior and Vital Immun formulas, and she’s doing great on both. While other dogs her age are already having trouble getting up, my dog shows no signs of that at all. I also find that Vital Immun really helps support my dog’s gut health. I love your products and will continue to buy and recommend them.

It helps!
My male dog is 14 years old and is now suffering from all sorts of age-related ailments. The Care supplement is working great for him. He’s also taking the vitamin B. He seems more lively again and enjoys going on longer walks!

Care for Seniors
I have to review this product too, because I’m really thrilled with it. They say natural remedies take time to work—but with my Bolonka, I already feel like he’s much more lively after just a few capsules. He runs like a young dog and is eager to go outside again. What great products! I just wonder why I didn’t discover them sooner. The customer service is also worth 10 stars—you really feel well taken care of here. I already have my eye on the next product, but my wallet needs a little break first. Thanks again for everything!

Very good
Hello, dear readers. I have a 12-year-old dog, and he’s been taking Care for 3 months. To say he’s “like a different dog” would be an exaggeration, but I feel like it’s really given him a boost. His joint problems have also improved—I’m thrilled. I’m going to try White Dental and Fresh next.

Highly recommended
My Stafford Terrier, who is almost 12 years old, has been taking the capsules for a good two months now. He seems much more energetic. I've already reordered them and can highly recommend this product.
— Automatic translation via DeepLThe 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.

Information for dogs with allergies: The glucosamine in DOG FIT by PreThis® CARE senior is obtained from crustaceans, the collagen from pork, the capsule shell from gelatine from beef and green-lipped mussel from mussel meat. CARE senior is also free from genetic engineering, yeast, soy, fructose, sugar, grain, palm oil and artificial flavors and preservatives.
Note: Our responsibility towards wildlife and the environment is our responsibility first place. That's why we make careful decisions when selecting our ingredients. We never lose sight of the principle of sustainability. We strive to use ingredients that are not only healthy, but also have as little impact on the environment as possible.
We take our commitment to environmental friendliness one step further. It is a clear priority for us to ensure that none of our ingredients come from protected animal species. This commitment reflects our deep-rooted respect for wildlife and is consistent with our commitment to ethical and environmentally conscious manufacturing. Chondroitins and gelatine are obtained from cattle, collagen from pigs.
For adult dogs of any size and breed. We especially have in mind dogs that are getting on in years and should be accompanied appropriately in everyday life – even without an acute reason. CARE senior is a complementary feed for daily feeding and no substitute for a balanced diet. If your bitch is pregnant or nursing, or your dog is currently under veterinary treatment, please discuss supplementary feeding with your veterinary practice first. You will find the right size for your dog's weight under “Dosage instructions”.
CARE senior 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.
This varies from dog to dog and depends on your dog's individual needs. As a rule, feed CARE senior for at least six weeks, in some cases longer. Natural formulations need time to unfold their supporting properties – regular feeding matters more than a high single dose.
One pack contains 60 capsules and therefore lasts around two months with daily feeding. If your dog receives an extra capsule according to the dosage recommendation, it will last correspondingly less. For continuous feeding we offer value packs.
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 collagen (beef) 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.
For further questions – such as combining several supplements, medication or the 5 + 1 deal – see our general FAQ.
