I have 2 well behaved small dogs. One is a 6yr old Shih Tzu Coco (he is super chill) and a 9mon Shih Poo (puppy energy). They need to be walked for at least 20 min . Coco wont walk more than 5 minutes but Ellie needs to walk at least 20 to 30 to get her bowels moving and release some energy. They both listen very well, just need the extra hand so my husband wont have to come for lunch every day.
