Because i will make their walk fell comfortable, no making them hurry and by letting them explore the area (always with their leash). Most of the dogs iv'e had taken care of, they become my family, i never forget them and i always treat them with love and patience, for me every breed is special. Sometimes i get attach to dogs that aren't even mine hahahahah. If the customer wants it i can take pictures and videos of their walks and games, so they can see first hand what i am doing, catching their moments so they can feel part of them. Finally i have experience with small, medium and big breed of dogs such as: boxer, schnauzer, yorsqhike, husky, terrier, golden retriever among others. Thanks u
