Footpad Infections (Bacterial Pododermatitis) --------------------------------------------- Serious (sometimes crippling) infections of the footpads are common among pet guinea pigs housed continuously on wire. The other major predisposing factor is fecal soiling of wire-bottomed enclosures. The front feet of overweight animals are especially vulnerable to this condition. Signs include swelling of the feet, lameness, reluctance to move, and inappetence. The flooring of the enclosure must be changed and overall sanitation must be improved. A veterinarian must be consulted regarding treatment of the affected feet. Topical dressing with an antibiotic and periodic bandaging are necessary during the usually lengthy recovery period. Injectable antibiotics are often used by veterinarians in treatment of this condition. Arthritis is a frequent and unfortunate consequence of these infections.
