Hello. Yes, your pet can pick up parasites from eating manure, but for the most part, parasites are host specific. Your veterinarian may see some eggs on Costa's next fecal exam, but your heartworm preventative will eliminate the parasites, so this is not anything to be concerned about. Thanks for using Petco Pet Education Center, formerly Petcoach.
