Brooke is absolutely adorable. The trim job is perfect.....just enough and what an adorable face. As far as the spayed, I am with you about being so nervous. It sounds like you have a great vet, my vet wants to keep my baby overnight.
I just don't know.
Has she continued to gain weight since you have had her? If so, I would wait alittle longer to see if she puts on more weight. I do agree though not to wait too long, What a difficult decision. Let us know what you decide.
