The pups really love that ramp. I put a cat sized tunnel in there with them but instead of going through it they played "king of the mountain" and all jumped on top of it lol. These are the bounciest puppies. They are like little kangaroos hopping all the time. It's cute until you are sitting on the floor with them and one of them tries to pierce your nose. Ouch!
They're lovely puppies - I love to see them when their noses are just getting colour. I think the tri girl looks very promising - have you a favourite?
Did you confirm pregnancy? You need to get her to a vet. They will probably need to do x-rays and if an ultrasound is available then ultrasound to check heartbeats for fetal distress.
