No, typically tick spray isn't fatal if licked. There is a potential it could have some toxicity, but the dog would have to ingest a large amount. Given that they lived outdoors and were strays, it could be that they got into something toxic outside, could have had a serious disease like parvo or distemper, could have been attacked by another animal, or could have been hit by a car. I'm very sorry they died. If you come across any more strays, I would contact your local RSPCA to come and get them. I hope this helps.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! How tragic! Yes, if the tick spray isn't meant to be sprayed on an animal it can be toxic. Also some tick and flea spray can only be used on dogs of certain ages. If you want to post the name of the spray we can help you better. I wish you the best!
