Comfortis side effects

I recently just purchased Comfortis for my bully. She was on Frontline every since she was a 6 months old but lately it was just not working.

The first day of me giving Comfortis to her, she was fine. Two days later I have notice she is eating less, leaving more than half of her food in her bowl, she is also extra lazier than usual. I am also in the middle transitioning her food from Royal Canin bulldog 24 to Wellness grain-free dog food.

Is it a common side effect for her to eat less with this medicine for the first few days or is it because she's transitioning her food that's causing her to not enjoy her favorite hobby...eating.

This month was first time Gunther used it

I gave it to Gunther for the first time this month and had no problem, thank God.  I just don't know what to use for ticks.

I would not use Comfortis

My cousin used it on her Chi and the dog lost huge patches of hair and became very lethargic. She stopped using the Comfortis and the hair grew back and she perked up.

Google Comfortis side effects and you will find that a lot of dogs have had problems and some have died.
