Collar Clinic is one of the nation’s oldest electronic dog collar specialists. Electronic dog training collars are a big investment, and there was a need for repair options other than the manufacturer’s service. Collar Clinic decided to meet that need. Our early customers also asked about adding collars or changing models for more range, and Collar Clinic stepped up again. Soon, Collar Clinic began to offer Guaranteed Reconditioned Trainers and within a few months became a dealer for new trainers too.
