fermentation after transfer and dry hopping?

[sdal]

Brewed an IPA. Lower OG at 1.052. Pitched two Wyeast 1272. Airlock activity began in a few hours and ended in a few days. After 8 days I transferred to secondary and dry hopped with 1 oz of Cascade pellets.
After transfer air lock started bubbling again and continues still 4 days later.(About 1 every 30 seconds)
Is this fermentation?

Probably not. Bubbles are useless for determining fermentation. You really need to do hydrometer readings to determine when the beer is done fermenting. Your beer is probably just off-gassing, quite normal especially after a transfer and dry hopping.

Thanks. I thought I read something in the past about off-gassing.
I will take hydrometer readings before bottling but was surprised to see it bubbling for so many days. Still going and it has been 5 days since secondary transfer.
