Condizione: New. Idioma/Language: Español. Muchos de los problemas de conducta más frecuentes que aparecen en el perro adulto se pueden prevenir, o al menos minimizar, estableciendo unas sólidas bases de adiestramiento desde la etapa de cachorro. Leslie McDevitt en Control sin correa presenta un programa para cachorros basado en mejorar la concentración, el autocontrol y la autoconfianza del perro. Prestar atención es una destreza con sus propios requisitos y debe enseñarse de modo separado al aprendizaje de otras conductas más complejas. El set de destrezas de atención incluye: destrezas de discriminación, destrezas de autocontrol y destreza de control de la excitabilidad, todo ello aplicando el principio de Premack y refuerzos positivos. Las destrezas de atención son la base para el adiestramiento. De este modo el cachorro estará preparado, a la edad adecuada, para el adiestramiento de algún deporte específico ?un cachorro con la habilidad de concentrarse siempre en lo que se le pide, durante el tiempo que se desee y en cualquier entorno. También encontraremos en este libro una interesantísima sección sobre Juegos y ejercicios para realizar con el cachorro. Los conceptos y sugerencias que se ofrecen en este libro son aplicables igualmente a perros rescatados y/o adoptados que, al igual que los cachorros, comienzan su adiestramiento en el nuevo hogar *** Nota: Los envíos a España peninsular, Baleares y Canarias se realizan a través de mensajería urgente. No aceptamos pedidos con destino a Ceuta y Melilla.…
