I am coming at this not from a Spriner POV but certainly a working dog.
I fell in love with Brittanys when I rehomed Mugi aged 10 - he was bright, lively and showed a whole heap of natural talent for what he was bred for. His father was a working dog into his mature years and his granny was placed in Field Trials. Mugi had obviously been well 'pet' trained and when you consider his age when I got him I am sure he would not have been a totally easy dog, even at 12 he loves to work and just today he gave the spaniels a run for their money in the Forest of Dean.
So knowing I had an old Brittany I went out to search for a young one with whom I could learn more about the working/trialling side of the breed. I was very lucky to be offered pic of a fantastic litter and I knew the pup would be 'hard work'. The breeder likens her dogs to driving a Ferrari after having a Family Saloon

I have had Chase now for nearly 18 months. I can say hand on heart he has not been easy, if I weren't stubborn I could have given up a dozen or more times. To keep him settled I do more work, training, activity, structured play than I have ever needed to do with a dog before.
He lives in the house and he has done all the same puppy stuff that previous dogs did although we spent weeks longer than some to get our KCGC Pup Foundation and in the end we were encouraged to leave class as Chase was classed as disruptive. This would have been less than helpful if I didn't have access to help from working avenues - if he were 'just' a pet he would undoubtedly be either a statistic in rescue or perhaps a dog that had been PTS for aggression as his frustration can lead to challenging behaviour.
I love him to bits, I want him to be a pet, a trials dog and a walked up shoot dog (oh and a show dog too

) - I am in for the long haul, I never expected an easy ride and he is certainly not giving me one. I am not sure I would deliberately seek out another similarly bred pup but I do enjoy this one
