Shower noisy when toilet flushed

I am remodeling a bath and need help with a possible venting issue. Over the past several years the shower drain gurgles when the toilet is flushed. The house was built in 1968. The bath has been gutted so I thought now is the time to investigate the problem. It is an upstairs bath that was all original. Is the vent clogged? Should I have it snaked through the toilet and shower drain? I never had a problem with the toilet being clogged in use. Please help.

The sink might be wet venting the shower and toilet. If the sink drain is partially clogged, that could be the problem.
