Welsh Springer Spaniel or Brittany?

I happen to like both and have had both. Your question doesn't give me anything else to go on concerning these two breeds.

Both are bird dogs in the sporting group. Talk to other bird hunters and trainers to learn the breeds hunting style to determine which breed will be the best match for you. If possible, go hunting with people who use these breeds to get an even better feel for them.

If you are hunting, the Brittany. If not, the Springer.

Depends upon you and your circumstances. Do you have kids, for example, are you an active person. Try http://www.bestfamilydog.co.uk/
