My dog has green liquid poop after Frontline. Is it the medicine?

Pet's info: Dog | Bull Terrier | Male | unneutered | 41 lbs

I have a 11 month old Bull Terrier Male, and he was given his last dosage of frontline plus flea and and tick protection, I noticed though his stool today was a liquid light green, is that from the medicine?

This is most likely not from the frontline but something he is eating. Typically, when I see light green stool in dogs it is from the greenies treats. I would look to see what extras Kilo is getting. Thank you for using Petco Pet Education Center, formerly Petcoach.
