關於 Frontline & Heartgard 問題

frontline and heartguard are totally different thing.
Have you start to look at the internet and do homework on it??
basiclly, frontline is for perevention of fleas, and ticks.
Heartguard is for heartworm, and roundworm.

2. 係診所買果啲, 盒上有衛生署Label, 喺咪因為咁所以貴咁多?
no, just people selling at different price. I would say buy it from vet clinic, at least they are more reliable.
