a mix of show/field springer would probably fit the bill. The show side tends to mellow out the active side of the field springer. They average 45-50 lbs, I'd say they are on the large side of medium in size over all. They are always up for a game of fetch, ball, frisbee, or a romp in the water or park. They are obedient and listen well if taught young, good natured, yet love to be with you and snuggle when you need them to. I find them a wonderful companion. I do have to caution as was mentioned already, make absolutely certain that you get one from a reputable breeder, ask about epilepsy, if there has ever been rage in the lines, or an eye issue called PRA. You also want to see the pedigree and make certain there is NO inbreeding in the lineage. For some reason springers, in my experience anyhow, do not fair well with temperament or health when there is any form of inbreeding in them. They do ok with a bit of linebreeding, but not inbreeding. Also I have found the males to be much more even tempered than the females and it doesn't seem to matter if the females are spayed or not. Most tend to get snippy with other dogs as they get older. The males tend to stay more even keyed their whole lives.
They need a firm hand for training but not a harsh hand. They respond best to praise as they love to please. Its' very easy to break a springers spirit if you are too hard with the training methods.
Brittany's, again in my experience, are very high strung, not quite as eager to please and many many of them have allergy issues. Although they are smaller than the springers are. The show brits are a bit more mellow, but if you get field in them watch out!
