Here is the big secret. It's a mutt. That is not a bad thing. It probably won't have any of the inbred problems that the high priced Breed dogs have and won't need that much special care anyways. Feed it decent food in reasonable amounts, make sure it gets some exercise and has fun.
In fact what you need to do to make sure it is healthy is the same things we should do for ourselves

So step away from the computer, get your fishing rods, the kid, dog and some bait (Oh, the horror) and go fishing.
I'm fishing around here as soon as I get out of here. There are some big Pike but I can't figure out how to post pics anymore.
