The most common house dog is called a Golden Retriever. A Golden Retriever was typically bread to hunt ducks and other small animals for sport. They are highly intelligent and often illegal drug sniffing dogs, search and rescue and guide dogs. There are three different types of Golden Retrievers: Canadian, American and British. My favourite is the British.As indicated by their name, their coat comes in light golden colors to dark golden colors. The coat is dense and waterproof, and may be straight or moderately wavy. It usually lies flat against the belly. Golden Retrievers are also noted for their intelligence, and can learn up to roughly 240 commands, words and phrases.The Golden Retriever's eagerness to please has made them consistent, top performers in the 1. obedience and agility rings. Plus with their excellent swimming ability they are great at dock jumping. Their natural retrieving ability also sees them excel in flyball and field trials.
