Yes, you will need a closer vet. And one major question I asked - do you do c-sections for emergencies - just in case. Most of the vets in my area do not do c-sections in off hours and I will never use the emergency vet clinic in my area again!! What dummies - based on what happen to me!!
Also - do not just look at photos - you really have to go to the shows and watch the movements, see color, texture of coats, etc... on the real thing!
