Carlos has been our personal doggy trainer for Nala who is now three months old. Carlos is incredible, his presence and manner in which he communicates with dogs commands attention. We have had three sessions with out little Nala, first he trained her to sit and she learned this lesson within a half hour. The second week he taught Nala how to walk on a leash, before I was just dragging her on the leash (gently of course) hoping she would understand but he showed me the best way to teach her was with positive reinforcement, patience and consistency. After two days Nala was walking perfectly on a leash! The third week he showed me how to walk both my dogs on a leash and how to stop Nala from trying to control our other dog Lulu. In all three weeks he explained the best way to potty train her and our little Nala can now hold it for up to five hours, I am no longer spending the entire day and night picking up pee and poop. Nala and Lulu love Carlos and I respect his kindness and gentleness. I highly recommend Carlos for any pet sitting or training you may need. He will teach you and help you with any doggy problem you might have. Thank you Carlos at wooftidoo pet services!
