XARTHRO joint tablets support your dog’s joint health with a carefully considered combination of native type II collagen and omega-3 fatty acids, which help promote mobility. The formula is supplemented by a variety of functional ingredients such as green-lipped mussel meat, seaweed, MSM, devil’s claw, glucosamine and chondroitin, which together provide holistic nutrition for the joints. The tablets are suitable for dogs of all breeds, are well tolerated, have a high acceptance rate and last up to three months for smaller dogs. XARTHRO is produced in Germany under strict quality standards, which speaks for its safety and effectiveness.
In tests, XARTHRO impressed with its very good acceptance, practical divisibility and pleasant size, even for smaller dogs. The effect on mobility and activity was noticeable. The low focus on sustainability and the product price were negative aspects.
Advantages
- Very good acceptance
- Good size, even for small dogs

As part of our testing of XARTHRO joint tablets, we examined their breakage resistance. The tablets showed no cracks or breaks, which is partly due to their high dry matter content. Dry matter describes the proportion of the mass without water. Our laboratory test showed that the dry matter content is 93.3 g per 100 g of tablets. The usual range of dry matter in food supplements is 85 g to 95 g per 100 g of tablet. This product therefore has a high dry matter content. A high dry matter value indicates a dense formulation with a low water content, which is typical for powders or tablets. In terms of acceptance, the product was completely convincing: all dogs tested accepted the tablets spontaneously and without hesitation. The product was also very well tolerated, with no signs of discomfort or behavioural changes. Laboratory tests have shown that the product does not contain any pesticides. Pesticide residues can be toxic and should be avoided in animal feed wherever possible (see European Food Safety Authority 2025). The fact that no pesticides are detectable is a strong indicator of quality (see European Food Safety Authority 2025). The value for lead measured in our laboratory is 0.14 mg/kg (equivalent to 0.132 mg/kg based on dry matter). The EU limit is 10 mg/kg. This means that the lead content is very low. Lead is a toxic heavy metal with no benefit for dogs (see European Union 2002, p. 15). The very low value shows that the product has been processed safely and to a high standard. The divisibility of the tablets was rated positively: they can be easily divided into two equal halves, which facilitates individual dosing and contributes to ease of use.
The joint tablets are of very good quality in terms of purity (no pesticides, extremely low lead content) and concentration (high dry matter content). The evaluation of the parameters examined indicates that this is a safe and well-processed feed supplement.

Prices of up to £0.70 per tablet are charged online for equivalent products. Very inexpensive products are available from as little as £0.40 per tablet. XARTHRO® joint tablets for dogs are therefore currently in the upper price segment at €0.58 per tablet. The price-performance ratio is very good for the quality and performance obtained.
