Welcome to YT.
Well, around June 10th you might have some puppies. Talk to your vet when he gets back. My Sunnie is 5lbs and she's had puppies. If she is pregnant, you'll get lots of help here.
I didn't want Sunnie to have puppies in the winter. Hubby thought that she was sad locked in the ex-pen so he let her out to "play". Obviously we both forgot to tell Rocky
about the "no winter puppy" plan. She had 2 puppies.
