How much does he weigh?? My Vet had my female on fluids and did blood work during the procedure because she was so small. I think if they do that there won't be a problem. It sounds like you picked a better Vet. You did nothing wrong the last time...the Vet should have known what to do. I'm so sorry for your loss. Congrats on your new addition. I'm sure it will all go smoothly.
