I have raised quality Jack Russel Terriers ( Shorties) for over 30 years. Have raised Australian Cattle Dogs for 15 years . I Gensol health test my breeding stock to avoid crossing two carriers of a single genetic trait with another. I only breed my females once a year and keep my babies in a clean, climate controlled building. Pups will have age appropriate vaccines and will have been wormed every 2 weeks.
This breeder hasn't written any updates yet, maybe ask them why?
