The term 'silky-coated dogs' refers to two breeds of dogs: Spaniels and Borzois. Spaniels are a type of gun dog, traditionally used for flushing out game birds. They have a long, silky coat that is usually wavy or curly. Borzois are a type of sighthound, bred for hunting in the steppes of Russia. They have a long, silky coat that is usually straight. Both breeds are known for their luxurious coats and make excellent companions.
