Your dog should have a routine veterinary checkup at least once a year, but the exact timing may depend on factors like age, health status, and any specific concerns raised during the last visit. Puppies, senior dogs, or those with ongoing health issues might require more frequent visits, potentially every six months or as advised by the vet. Regular checkups help monitor your dog's weight, dental health, and overall well-being, ensuring early detection and prevention of any potential health issues. Always consult your vet for personalized recommendations.
