Finally took the time to go through some of your threads. I relate so strongly to puppy Watson's antics.
His calm overall puppy nature, disinterest in toys, refusal to settle, and barking at the bunnies (or in my case kitty) all are very similar to Sansa.
Though I can force interest in toys if I'm willing to be more active during play time than she is haha.
Just wanted to say, I think your Welsh Springer Spaniel is so cute! I love your sig picture! I'm curious as to why you decided to go with a Welsh instead of an English? I wish there were more of them around, I've never seen one in real life, only admired them in dog books.
