Yes... I hope the cleaning is very uneventful and it goes well. I know that if our dogs ever have a bad experience with the vet, it is "all over". They don't ever want to go back and seem to have very good memories about different rooms and needles, tables, etc. Anything that was unpleasant, they seem to remember and if we are at the vet and they open the room for where something did not go so well, they immediately start to cry and start to pull away and want to get "out". They are SOOO smart and really do have good memories. Good luck!
