Print match and line after

I have some data where the 4th column will either be frz or -. I would like to find all lines where the 4th column is frz only if the 4th column on the next line is - and then print both lines.

Sample input:

2018-04-09T14:15:23.366Z  7 multi -   uuid1 uuid2 uuid3 -
2018-04-09T14:15:23.978Z  8 multi frz   uuid1 uuid3 -        -
2018-04-09T14:29:35.826Z  8 multi frz   uuid1 uuid3 uuid2 -
2018-04-09T17:19:01.901Z  8 multi frz uuid1 uuid3 uuid2 -
2018-06-03T22:12:38.688Z  8 multi -   uuid1 uuid3 uuid2 -
2018-06-28T00:35:54.338Z  9 multi -   uuid1 uuid2 -        -
2018-06-28T00:47:51.679Z  9 multi -   uuid1 uuid2 uuid3 -
2018-06-28T00:47:51.720Z 10 multi -   uuid1 uuid3 -        -
2018-06-28T00:47:58.863Z 10 multi -   uuid1 uuid3 uuid2 -
2018-06-28T16:29:01.624Z 10 multi frz uuid1 uuid3 uuid2 -
2018-06-28T17:29:01.624Z 10 multi - uuid1 uuid3 uuid2 -

Expected output:

2018-04-09T17:19:01.901Z  8 multi frz uuid1 uuid3 uuid2 -
2018-06-03T22:12:38.688Z  8 multi -   uuid1 uuid3 uuid2 -
2018-06-28T16:29:01.624Z 10 multi frz uuid1 uuid3 uuid2 -
2018-06-28T17:29:01.624Z 10 multi - uuid1 uuid3 uuid2 -

I've found a few awk commands to print the line after a match but I can't figure out how to match both lines and print both.

What I currently have:

$ awk 'f{print;f=0} $4=="frz"{f=1}' input
2018-04-09T14:29:35.826Z  8 multi frz   uuid1 uuid3 uuid2 -
2018-04-09T17:19:01.901Z  8 multi frz uuid1 uuid3 uuid2 -
2018-06-03T22:12:38.688Z  8 multi -   uuid1 uuid3 uuid2 -
2018-06-28T17:29:01.624Z 10 multi - uuid1 uuid3 uuid2 -
