Aside from humans, dogs are regarded as the next-best ideal companion, because of their loyalty, consistency and generally pleasant demeanor. They have been used as therapy pets that show unconditional love for their emotionally suffering masters; dogs have also been loyal cohabitants for the elderly, and a comforting healer for those who have been bereaved. Canines have also been considered the perfect cohort for runners and those with an active lifestyle, or owners who enjoy company on their errands and outdoor hobbies. For those looking for a comforting dog, there are small breeds and lap dogs (such as Pugs, King Charles Spaniels, Shih Tzus) that are content to cuddle by your side. Gentle giants (such as Newfoundlands, Great Danes, Retrievers,) also bring a steady and comforting presence to their masters. Owners looking for an active partner to keep up on their morning run, or who will want to catch a Frisbee in the park, there are large breeds (like German Shepherds, Vizslas, Australian Shepherds, Border Collies, Retrievers, and Schnauzers) and small breeds (like Jack Russell Terriers, and Corgis) that bring tireless energy to any activity their master can muster.
