They possess great intelligence and a readiness to accept training. Their qualities as a companion are unsurpassed. The long silky coat of the Yorkie distinguishes it from all other small breeds. However, this lustrous coat will only look it's best with regular grooming. Yorkshire Terriers are best suited as house dogs. Yorkies generally weigh 2-7 pounds at maturity.
