Keep an eye out for general physical or functional changes in your pets body, such as sudden weight increase/decrease, vomiting, changes in stool, difficulty breathing, or issues with skin & coat health to ensure your pet lives a long, happy life. If these problems are chronic or persistent, be sure to visit the vet for more guidance. If medication is needed, you can always ask your vet to fax the prescription to PetsDrugMart for a lower cost, home-delivery pet medication option.
