Help!!My dog licked D'mag spray, restless and drooling

My dog have injury near his private area, today I have sprayed dmag spray around 10:30 after that he licked it

Now he is restless, drooling and having high heart rate

It's almost 12 now

Talked to the vet he said let it be he'll be okay but google says its poisinous

What should I do

My dog is 8 year old, healthy indie male

He is fit and quite healthy

But right now restless and breathing heavily

Also the spray has manufactured on feb/jan last 2025

And have shelf life of 18 months

So it may be last month of its expiry

I also talked to one of my animal rescuer friend she also said let him take his time it's harmless

But google say otherwise

I'm so much in distress, also my boy help if u have any information regarding this situation
