It’s good to check pets for parasites if that’s an option for you. If not, be sure they are on a natural diet. Dogs and cats eat raw meat. That’s their diet, not grains or cooked dog food. Optimize your pet’s health, and hey, they’re part of the family. The only advice during the program is to not let them sleep in the bed with you (if possible— we understand if it just won’t work suddenly for Spot to be kicked out of his bed ;).
