Congrats!!!
I live in Manhattan(UES as well) and as you know $$$ is crazy in the city.
Specially good vets can cost your arm & legs

.
carnegie hill veterinarians in USE is very good place.
I personally use humane society, cause not only they are reputable, but cost about half the regular vet.(just need to call 2weeks prior to appointment) Don't forget to enjoy (9am~9pm) dog walk with your baby in central park! Good luck with your new baby!
