here is the answer
in the first group 3 dogs can receive the award in 6*5*4 = 120 ways
in the second group 120 ways
total ways = 120*120= 14400

In the first group, winner group containing 3 dogs can be formed in 6C3 ways - prizes can now be distributed in group 1 in 6C3*3! ways = 120.
In the second group, winner group containing 3 dogs can be formed in 6C3 ways - prizes can now be distributed in group 2 in 6C3*3! ways = 120.

Total no of ways in which prizes can be distributed in group 1 & group 2 together = 120 * 120 = 14400
