Back trouble is another problem. One of ours has invertebral disk disease. Hip displasia should be checked as well. One of ours has mild hip displasia. There can also be eye problems.
Cavaliers are beautiful, happy, extremely loving little dogs, with an enthusiasm for life.
Cavaliers can also have hip dysplasia, luxating patellae, various eye problems, back problems and epilepsy. They use those beautiful faces to get what they want, and require real diligence to be truly house trained. They are smart and excel in both obedience and agility. A big dog attitude in a small package. Our Cavalier King Charles is the most wonderful dog we have ever had.
