I spoke to my Vet today and she is fine with doing the blood work one week prior to dental and ultrasound.
I did ask if they use anesthesia or sedate the dogs when doing the ultrasound and she said they try not to unless the dog is being uncooperative.
Thumper has always had the two procedures together so I did not realize he was. not under anesthesia for the ultrasound. What they do is the teeth cleaning first and as he is coming around they do the ultrasound. She said the dogs are usually sedate do to the meds so it is easy for them to do the procedure at that time.
I plan to make an appt in July/August. The vet's schedule is changing on a weekly basis and since I want my specific vet to do the entire procedure I cannot make the appoint too far in advance.
Unfortunately, Thumper does need yearly teeth cleaning I previously went three years without any and he needed 7 extractions. I can see the tarter on his teeth. Even with me brushing them they are bad.
Thank you all for being my sounding board. I love my vet and that she listens to my concerns.
