I have a 8 month old female lab and my problem is that she LOVES water retrieves but on land it's a different story. On land she does ok but will only retrieve a couple times then she gets lazy and lays down with the bumper but when it comes to water she gets very excited and brings the bumper back and starts looking for another one to be thrown. So my question is.....should I be concern? Do I need to do anything to make her more excited about land retrieves? Also kind of a off question but while I do obedience training do I stop all retrieves or just do a few here and there?
