(reactions)-flea and tick drops for dogs?

if a dog would have a reaction to them, what would be the symptoms and how long after you apply would you see them?

You can see a reaction within minutes of putting on drops. Red skin, itching, whining are a good sign of an allergic reaction.

they will be very tired, seem very out of it and they wont want to eat or drink, they will be very weak. you will see syptoms within 12 hours depending on the size of the dog. if they get any of the symptoms immediatly give them a bath! use regular dish soap like dawn or palmolive and wash them very good to get the oil off and they should start feeling better within a couple hours.
