The term 'Petite Pooch' refers to three different breeds of small dogs. The first is the TOY, which is a breed of small dog that typically weighs less than 10 pounds and stands no taller than 10 inches. The second is the Peke, which is a breed of TOY dog that originated in China and is known for its long, silky coat and large eyes. The third is the SCOTTIE, which is a breed of terrier that is known for its strong, muscular body and wiry coat. All three of these breeds are considered to be petite pooches, as they are all small in size and make great companions.
