The news that Lamb's Dally M winnings was more than his contract ensured that he would be in hot demand from the richer Sydney clubs now that he was out of contract and that
Wests were at first expelled from the premiership.
Easts and
Balmain both showed interest but eventually Lamb chose the Bulldogs, joining in 1984. Lamb settled nicely into Canterbury under the coaching of
Warren Ryan and playing outside
Steve Mortimer. Lamb's arrival did cause initial controversy when long-serving five-eighth
Garry Hughes was dropped to reserve grade in what was to be his final season. Lamb's ability to back up the ball-carrier came to the fore as he was the Sydney Premiership's joint leading tryscorer with 17. Lamb won a recall to the
New South Wales State of Origin side for the 2nd match. He played well enough to be retained for the 3rd match despite the Blues losing, but withdrew due to injury. Lamb never won a junior premiership and he was closing in on one at senior level when the Bulldogs made the 1984 Grand Final against arch-rivals
Parramatta Eels who were looking to win their fourth successive title. Canterbury took out the Grand Final 6–4 in a bruising game of football. Lamb was replaced with five minutes remaining due to a nasty gash above his eye. In 1985, Lamb played 22 games for the Bulldogs, but was forced to miss the 1985 Grand Final due to a groin injury.
Michael Hagan was named as his replacement. Canterbury defeated
St. George Dragons 7–6 to make it back-to-back titles. 1986 was an eventful year for Lamb. He played much of the opening rounds at halfback with captain
Steve Mortimer suspended, and was recalled to the
New South Wales State of Origin side. He was selected in all three matches from the bench and went on to be selected in the
Australian Test side for the opening match against New Zealand. Lamb came on from the bench as a replacement for
Dale Shearer. Lamb got more time in the 3rd Test when he came as a replacement for the injured
Wayne Pearce playing lock forward. His good form at Canterbury continued with the Bulldogs making a third successive Grand Final, once again playing
Parramatta Eels. Lamb was the leading pointscorer for the season, and he would end up scoring 210 points. However, he missed a difficult penalty goal attempt in the final three minutes of the 1986 Grand Final. The Eels won 4–2. Lamb was then selected to go on the
Kangaroo Tour. In March 1987, Lamb scored all of Canterbury's 26 points as they beat Wests 26–16 in round 4. Lamb's points haul were made up of four tries and five goals. He again finished the season as the leagues leading try-scorer however, the club failed to make the finals, finishing 6th in what would prove to be Warren Ryan's last season as coach.
Warren Ryan departed Canterbury at the end of 1987 with reserve grade coach
Phil Gould taking over the reins in a caretaker role with
Chris Anderson being groomed for the top position. ==Hanley incident and the World Cup==
