Brittanys make excellent gun dogs and even better family dogs. We have had up to 3 in our home at one time. You (AND YOUR WIFE) cannot be afraid of dog hair. Regular brushing helps, but it is something that Brittany owners have to put up with if they live inside.
I have trained and hunted over six Brittanys over the past 40 years ... my brother had another 4. I am by no means an expert, but all my dogs naturally pointed and only became more staunch as they gained experience ... Some of my Brittanys were very good waterfowl retrievers (both over water and grain fields) when I did more waterfowl hunting. Not a replacement for a lab, but can do the job if you watch what temperatures they are exposed to.
The one caution I give to potential new Britt owners is they are very tender-hearted and you cannot discipline them like many other breeds. A load voice is all that is needed and sometimes that may be too much. I have never used any electronic training collars.
