Why is there a red, growing bump on my dog's ear that looks like a pimple?

Pet's info: Dog | Labrador Retriever | Male | neutered | 5 years and 7 months old | 90 lbs

I just noticed a red bump on top of my labs ear the other day. I checked it again today and it seemed to have gotten bigger. Looks like a pimple but no center to be seen. Cant see a bite either. No puss or anything. And it is very red. What could this be?

It could be an aural haematoma. If this is the case, the blister will contain blood and it is likely secondary to shaking his head or/and scratching of the ear. I would recommend to have him checked over by your vet, he might have an ear infection that requires treatment.
