Dolfos Dolvit Senior Plus, 800 g is a balanced vitamin and mineral complex for senior dogs from the Polish maker Dolfos. It's designed with age-related metabolic changes in mind and contains glucosamine for joints, arginine, vitamins, minerals and antioxidants. It's enriched with natural ingredients: ginseng, cranberry, tocopherols and capsaicin. According to the manufacturer, the ingredients support joint mobility, strengthen immunity and help maintain vitality.
What changes in a senior dog
In dogs over 7–8 years old (earlier in large breeds), metabolism slows, mobility decreases, joints work less well and immunity weakens. Digestion changes too, and vitamins and minerals are absorbed less efficiently. That's why senior dogs are often advised to eat a senior food and, where needed, take a vitamin complex. More in senior dogs: diet and care.

Pros
- For senior dogs. Designed around age-related changes.
- 200 mg glucosamine. Joint support.
- Vitamins and minerals. A full complex in one tablet.
- Antioxidants and plant extracts. Cranberry, ginseng, tocopherols.
- A yeast base. Dogs eat the tablets as treats.
- A big pack. 800 g lasts a long time.
Cons
- Confusion on the product page. Mini-tablet values are listed alongside the main figures, and the number of tablets per tub isn't stated.
- No chondroitin. Only glucosamine — dogs with joint problems need a separate supplement.
- A high price. An expensive pack.
- A vet is needed. Senior dogs with kidney or heart disease need supplements chosen individually.
Dosage
1 tablet per 10 kg of body weight a day. A 20 kg dog gets 2 tablets, a 30 kg dog 3. Give as treats or crumble into food. Discuss the course and breaks with your vet, especially if your dog already takes other vitamins or a prescription diet.
Senior dogs' joints
The glucosamine supports cartilage, but with marked lameness and pain it may not be enough. In such cases a vet may prescribe a full joint supplement such as Dolfos ArthroFos and pain relief. More joint supplements are in the dog joint supplements collection. Keeping a healthy weight and giving manageable exercise — short but frequent walks — matters too.
Feeding a senior dog
The basis of an older dog's health is the right food: moderate calories, quality protein and joint support. For example, Brit Premium Senior S+M. More options are in the senior dog and cat food collection. If your dog eats such a food, vitamins aren't always needed — decide together with your vet.
Storage
Keep the tub tightly closed somewhere cool and dry. Yeast tablets smell tempting, so keep them out of your dog's reach — eating a whole tub at once risks a vitamin overdose.
Who it suits
Owners of older dogs, especially those with reduced mobility, weakened immunity or poor appetite. More supplements are in the vitamins and mineral supplements and dog vitamins sections.
Verdict
Dolfos Dolvit Senior Plus is a vitamin and mineral complex for senior dogs with glucosamine, arginine, antioxidants and plant extracts on a yeast base. Convenient support for joints, immunity and general wellbeing. The downsides are confusing mini-tablet data on the product page, no chondroitin and a high price.
