With a full-time job and busy family, many people opt for a low maintenance pet like a cat. But circumstances change and many an animal lover's thoughts then turn to getting a dog. This faces them with the problem of how to stop cats and dogs fighting like...ahem...cats and dogs. Most dogs can learn to live in peace with a cat, however, some dogs are tougher to train than others. For example, terriers are hard-wired to chase down prey, and seeing a moving target such as a cat, pushes their 'chase' button. If you are in the position of weighing up which dog to get, one option is to make life easier for everyone involved and avoid terrier breeds. Also, starting out with a puppy is a lot easier than re-educating an adult dog. Puppies that are still within their socialization period (the time when they accept what they see around them as normal) are much quicker to catch on that the cat is a family member and not a toy to chase.
