Common Traits of Rat Terriers and Chihuahuas

Before diving into the distinctions between these breeds, let’s first explore some shared characteristics that can help you determine whether either of them is a good fit for your home:

  • Size: Although there are size differences between the two breeds, both rat terriers and Chihuahuas are considered small dogs. This makes them excellent choices for apartment and city living, as they have moderate exercise requirements. A brief daily play session is usually enough to keep them content, and they don’t require a large yard.
  • Intelligence: Both rat terriers and Chihuahuas are remarkably intelligent breeds, making them relatively easy to train. They have good attention spans and can excel in training with the right approach, although gaining their respect may require some effort.
  • Pack Mentality: These breeds share a strong pack mentality. Once they recognize you as their family and sense your affection, they become loyal and devoted companions. They tend to be affectionate with those they trust, although they may be reserved around strangers.
