It's VERY important to build up your money before starting the boss fight. If you aren't able to stack up your DPS somewhat before reaching the enemy base, then it's going to be very hard to quickly kill the Razorback. Wipe out the Two Can with your heavy hitters, and then the Tackeys shouldn't be much of an issue. If you have difficulty with the Two Can, then use an Octopus Cat to shield your units from its Wave Attacks and allow them to get their attacks in, as Pizza has trouble hitting Two Can if the Wave fires off every time, even with level 40+ units.

Do note that this stage sends out Razorback & Two Can twice each, so make sure that you can either destroy the enemy base in time (you have around 8 to 12 seconds for this), or that you have enough power to knock out one of them when they spawn for the second time. This stage also heavily relies on timing, so try it a couple times to see when you need to spawn your freeze units. If you can time your Octopus Cat and Bombercats correctly, you should have no trouble.
