Hello. Thank you for using Petco Pet Education Center, formerly Petcoach. Great question. Yes, they should be fine. If you gave the cats dog dewormer that would not be good. Do not give the dogs any more dewormer at this stage. Wait at least 7 days before you give them the correct dewormer. Hope this helps. Best wishes.
