Penny, the puppy my brother found a few weeks back has doubled in size but fits right in with our family. It doesn’t bother her whenTina, the older female snarls at her nor does it matter when my male dog Rusty fusses at her…she just keeps on playing and nipping at them. Her feet seem huge to me. Not sure what kind of dog she is mixed with but I’m thinking she may be bigger than we expected. 🙂
