Apologies to Ms. cC for the slight thread diversion...
Mr. CP. I suspect the "lobster dog" in the GIF is a Labrador Retriever (black variety). Great dogs for going and getting things they can see but not much for actually FINDING anything out of sight. That being said, they have been extensively and very successfully trained and employed as guide dogs for the blind and as well, they and their close relatives, yellow labs, are one of the most popular breeds in North America.
Redbone Hounds, on the other hand, are bred, born and raised to seek out and identify a plethora of "quarry" be it (ra)'coons, mountain lions, bear and deer to name a few. A number have also been trained in search and rescue.
They can be a very vocal dog during the chase so I suspect IF a Redbone were to go after a lobster it would, unfortunately and most probably drown...bark/bawl out, water in-alas, end of story.
Lobster are most possibly one of the few prey that Redbones could not be used to hunt thus I would encourage anyone thinking of using their Redbone to hunt bugs that they attend the webinar instead. Follow the link in post #7 please.
