My dog has Nexgard, but I'm still seeing ticks. Is this normal?

Jeter is on Nexgard but we're still finding ticks on him. How is this possible? Can they just not bite him? What's the story?

Hi there. Nexgard is a very effective medication for ticks, but the tick will bite and remain attached for several hours before it absorbs enough of the medication to kill it. So you may still find unattached ticks crawling on your dog, small attached ticks that are still alive, or attached ticks that are already dead. This is normal.
