-What is a dental therapy dog?
Dental therapy dogs provide comfort, affection and support especially in stressful situations. Anyone that is a little nervous about visiting the dentist should experience the comfort that our therapy dog Zeus, can provide.

-Why does Zeus wear a harness?
- The reason for Zeus wearing a harness is to let him know he is in 'work mode'. 'Work mode' means Zeus needs to behave in a certain way in a certain environment. Once the harness comes off, Zeus knows he can go back to being a regular dog.

-Where does Zeus live when he isn't 'working'?
Zeus lives with the owner of the practice, Dr Sara and her family. Sara has 5 kids so Zeus is never short of entertainment. Zeus also has an brother dog named Loki who is a cavalier x pug.

-Can i pat Zeus?
Yes! Zeus loves a pat and a cuddle while you are waiting for your appointment. You will find him lying on his bed in Sara’s office having a snooze inbetween meeting lots for new and amazing people.

If you would like some extra attention during your appointment, you are more than welcome to take Zeus into the appointment with you.
