Credelio for dogs, like other oral flea and tick preventatives, may cause side effects such as vomiting, diarrhea, decreased appetite, and lethargy. In rare cases, neurological reactions like tremors or seizures have been reported, especially in dogs with a history of such issues. Always consult your veterinarian before starting Credelio to ensure it is safe for your pet.
