  • Iguanas make fairly good pets for the right owner. Since they can live up to 15 years and can grow up to 6 feet, proper housing and space must be considered for long-term care. Proper care, housing and nutrition is essential to help your iguana live a healthy life.

  • Iguanas face several health problems that need veterinary intervention for treatment or resolution, including cystic calculi, Salmonella, avascular necrosis, abscesses, and dystocia. Understanding these problems helps you better care for your pet and minimize future health concerns.

  • The iliopsoas is an important core muscle. Injury can occur due to trauma, but it is usually caused by chronic stress. Signs that your dog has a painful iliopsoas can include reduced performance (if a sporting dog), very subtle weight-shifting away from the affected side when standing, or an obvious limp. The initial treatment for acute iliopsoas injuries is activity restriction and pain control for 10-14 days. Rehabilitation therapy can also help.
