Medium white dog loose in Regent Park

Around 8:20am, saw a medium sized white dog (maybe 20lbs?) with a purple/pink leash attached running west on St David's st. I tried to grab their attention with a peanut butter sandwich, but they only paused then kept running. The dog seemed kind of frantic as it was running at a pretty good pace.

They turned north on Sackville. They may have turned east on Dundas or continued north on Sackville (there were too many parked cars for me to confirm).

Just thought I'd post in case someone just had their dog slip away from them in the area.
