springer here.
He is playful and nosey and always wants to be doing whatever I am doing. This may or may not be what you want.
He is loyal to a fault (i.e. I often step out of the shower to find he has relocated himself to sleep just outside the bathroom door).
He is really affectionate and loves to be touching the people he loves.
He is pretty quiet, even with the 'bad' influence of two older and barky JRTs. He rarely reacts to anything in the garden, such as pigeons, squirrels or the dog over the fence barking at him.
He hates being left alone with a passion, to the point it would be an issue, except there is always someone in here.
I walk him twice a day, for about an hour each. Mostly off lead. We also do about 30 mins of training/play per day. I love walking so that is a factor but I also struggle to imagine him coping with less on a any regular basis.
Training him has been easy - he loves to learn, loves to get things right and loves to be doing something with his human. However, if I were a "telling off" kind of trainer I could well imagine him to hate it. He is pretty sensitive to getting things wrong and even without punishment can be visibly stressed if he doesn't guess right what is expected of him.
His nose leads him astray. Once it is switched on, his brain and hearing goes. He loves to sniff and walking can take ages if there are lots of exciting scents.
His adolescence started at around 10 months old and lasted until he was about 18 months. He was a pita for much of it. We used to describe him as having an "edge" to him on particularly bad days. A stubborn, highly strung, highly boisterous edge in which he didn't care if he bowled people over or got into trouble. Bull headed. Pacing. Always looking to be doing or for mischief to get into. Deaf on walks.
Now we are through it he is much better, gentler, happy to settle etc. but still an energetic young dog.
