My pug dog LOVES the dremmel, and she's a scaredy cat when it comes to most things. Missy however, hates it. So, I just clip the tips of her nails once a week with human nail cutters because she's quite tiny. The vet commented on what a great job I'm doing with her nails
I don't think that I'd do the whole cauterizing thing. I mean, I'm sure it can be done, but why put her through that when she's already getting spayed. I wish her a speedy recovery.
