if i were were you i would go for a lab mate, there easier to train/handle than most other breeds and are are bred for retrieving from water ect. i wpuldnt keep it in the house though, it'll just end up spoiled, to much attention can be a bad thing imo for a working gun dog.
I'm no expert mind, just training my first gundog myself !
