Causes: The three main types of arthritis in dogs
- Bacterial arthritis: This form occurs when bacteria enter the joint – perhaps through an injury, surgery, or via the bloodstream. The inflammation often leads to the formation of pus, which can damage the joint cartilage. Bacterial arthritis often occurs in people with a weakened immune system and is considered an emergency that requires veterinary treatment.
- Fungal arthritis: Fungi – especially yeast – can also spread throughout the body and cause inflammation in joints. This form is rarer but also problematic, as it often becomes chronic and places long-term strain on the tissue.
- Rheumatoid arthritis: This is a misguided immune reaction. The immune system attacks the body's own tissue – especially the synovial membrane. The result: a restricted supply of important nutrients to the cartilage. If left untreated, this can lead to long-term cartilage degradation.
Observations in dogs
If the dog suddenly walks more stiffly, joints appear swollen, or behavior changes occur (e.g., withdrawal, reluctance to go for walks), joint inflammation may be present. A precise diagnosis is made by a veterinarian – often with the help of blood tests, X-rays, or ultrasound.
Attentive attention to the dog's individual needs, regular exercise, and loving companionship in everyday life can contribute significantly to maintaining your four-legged friend's zest for life, even with age-related changes. Working with experienced professionals and adapting the living environment early on helps ensure the dog has as much comfort and mobility as possible.
You and your dog: Every day with your dog holds both small adventures and big moments. With patience, care, and an open mind for your four-legged friend's needs, you strengthen your bond and provide security. This way, your life together remains full of trust, joy, and shared discoveries—for a wonderful time together.
