RE: Dogs ?
All dogs - no matter what the breed need coat servicing. Is part of taking good care of the animal.
One simple thing I do with mine is use a hacksaw blade as it removes loose fine under hair really nice.
Now for breed of choice - all hunting stock dogs can be trained to do both grouse or ducks. Depends on whether you want a pointing dog or not.
I suggest - go take a look at a few different breeds at the many dog events that one can compete in - then do some research on a few breeds as you choice narrows down and then make your choice.There are many great reputable breeders out there!
Saying one breed is better than another is hogwash and starts board wars. Each of us have chosen a breed we like as it is our choice.
