I think there are only two totems that you need to worry about as a lock.

Grounding totem - as mentioned, and I think the tremor totem (something like that).

Macro that up - so you can target grounding, then tremor..... either sending the pet on it.... or wanding them. ( or a macro that sends pet to one and wands the other). Not too sure. Sounds like you are far more experienced than me so you've probably tried all this.
