My dog just had his first dental cleaning with Janssen, it went well. He was a little groggy and obviously had some minor pain first night. He did well and was back to himself the next day. I really didn't want to schedule this appointment as I have had bad experiences in the past with a different vet but I am now confident Janssen did a good job. They are a little aggressive on making appointments but I also treat this as getting my dog and cat vaccines done and always up to date.
