Oh my, the pups have come alive. They are no longer content to be pen puppies. With the miserably hot weather, they were getting lots of inside puppy play, but have tried to get them out early AM and late PM. Yesterday, I had two puppy mishaps. I was getting ready for work and the pups were loose inside. However, I was surprised to hear a puppy crying from out in the backyard. I looked out, and found Sierra out in the backyard. Apparently she had followed Yoko out the dog door. Then when I put all the puppies back in the pen, I came up one pup short - Vallejo was missing. I looked all over the house (and I have a number of rooms shut off), and no puppy. Finally, I checked in my walk-in closet which I thought I had closed, and found Val sleeping in the corner. Crate training aka feeding in the crate has begun, and the pups are perfectly fine with the new routine. Yoko is complicating matters by trying to help out with the kibble feeding. She regurgitated some of her breakfast for the pups this morning. She also did this with her first litter. So I will start limiting her access to the pups 4 hours after feeding. Yes, it is a very natural process, but the adult kibble size is too big and the pups may choke, and it is impossible to regulate the amount if Yoko assists.
