Two pounds is small, but if it makes you feel any better, I had two pet rats who were spayed-- they weighed only half a pound each.^^;

Make sure that the vet you take them to uses a protocol that is very safe (pre-op bloodwork, IV fluids during the procedure, Sevoflo as a lower-risk gas anesthesia, adequate pain control during and after surgery) , and things will hopefully be fine. Just make sure you're comfortable with the vet, and educate yourself as to how the protocols they use impact the safety of your puppy. There's more than one way to anesthesize and spay a dog, and some vets use safer and more humane protocols than others.
