Bonny - I think a " little" sedative is good. My vet only uses it if he has too. The vet doesn't want any tears, etc. that is why he want' them relaxed. Bonny is like any miniature sometimes they will through a little fit - they don't like it. So, it is something you have to be careful about. They won't mean to hurt you - but, they will wheel (sp) to get away.
My vet won't come to our house he is too far away. So, of course he has a set up for the ultrasound. While waiting on the vet ( you may have already done this) I would be looking around for the safest place for Bonnie- you- and the vet - to tie her up.
I am going to try and figure paint out today ( It is sad - that I don't know how to use paint).
I don't think you will mind - I am going to try and use some of your pictures and then post them.
Just in case - will you let me know if this is ok?
