I’m on my fourth springer spaniel - I adore the breed - got her when she was 10months old and completely clueless. Long story short she has gone for a dog while loose running ie completely unprovoked, nowhere near her etc. I absolutely grovelled - as I should have. This can’t happen again so she will be on a shorter lead - per usual- for path walking, and a longer one for rough terrain. Those of you who know the breed know how much running and water and muck is for them - but there really is nothing I can do is there? She is an affectionate obedient fantastic family dog.
