Angry Dogs since Heart Operation

[CyclingTime]

Hi this may seem random!! Since I had my bypass operation 3 years ago small dogs especially have been very very aggressive to me, I have been bitten three times. It happens nearly 90% of the time with them and it's causing me stress.

I am on Omeprazole, aspirin, statins and tamuflosin.

Has anyone else experienced this at all ? I can't believe it's a coincidence, I'm assuming I am giving off some smell that dogs can pick up and it's causing this issue!!

Thanks in advance
