<human>: I'd like to know what to do when my dog has worms.
<bot>: The first thing you should do is take your dog to the vet for a checkup. They will be able to diagnose any worms and provide treatment if necessary. You can also try natural remedies such as garlic, wormwood, or black walnut hulls to help get rid of the worms in your dog's system. Additionally, make sure that your dog gets plenty of exercise and proper nutrition to keep their immune system strong.
