When all the humans have been helped, then we can turn our attention to dumb animals.
We're talking about privately funded efforts here.
How on earth is having a few privately funded animal rescuers, pulling stranded animals out of the water, going to hurt the effort to rescue humans?
And as I pointed out above, the animal rescuers will very likely be able to pinpoint the location of stranded humans too (quite possibly rescuing some humans themselves --and if that's not possible, they can relay the stranded persons' locations on to the Coast Guard and National Guard).
