Hi Julie and Boomer! We used to have a corgi named Boomer too! and we named her after that character on Battlestar Galatica too!! And she was almost all red and sable too!!!! But sadly, our Boomer was killed in a tragic car accident. She was only about 16 months old. We still think of her and recount her funny moments and antics everyday. Your Boomer really reminds us of ours... =)
It is not uncommon to have a setback in housebreaking at about 5-6 months even without the surgery. I would expect that it is temporary and she will get back on track very soon! Nice pictures. Boomer is very cute! If you figure out how to get her to stop chasing cats let me know. With ours it is a pafk mentality and the barn cats egg it on.
