I'm not a breeder but when Maddie was born I was very fortunate to be there.
The mom also only had one pup and weighed aroung 5 lbs. Maddie was 5 oz and her mom Mia did have some problems delivering. It was a little scary but Mom and baby were both fine. The breeder was in contact with the vet and ready to bring Mia in.
If you aren't sure - I guess I'd be prepared. Mia's owner certainly was and it help to avoid any problems.
