My lab pup is now 15 wks old. I have been working on retrieving almost every day for about 8 wks but also trying to keep it fun and positive, no scolding or reprimands. The training videos and books I have say not to "burn your pup out" , the problem is I can't seem to get the fire lit. He'll retrieve 4 maybe 5 times and the retrieves are only about 10 feet or so and then lays down. Am I expecting too much too soon or should I try something else? Also he pays almost no attention to his retrieving bumper but works with a ball. :help:
