[Bay-Bay]

Little Bailey has 2 baby teeth that need to be taken out, as her adult teeth have come in right behind them. The vet said that they could do her teeth and spay her at the same time. I, however, am scared to have this done.
Bailey is now 8 months old, definitely old enough to be spayed, but she only weighs 2 pounds. I am worried that because of her weight, they might give her too much anesthetic.
I know those teeth have to come out, but I am too scared to make the appointment. Any advice?
