I have got to bath my dogs every now and then! If I dont they get to stinking so bad I have to feed them with a slingshot!
They may get a bath on average of maybe 3 times a year but thats it. I have noticed that it make them feel better after several days of hard hunting in the muddy bottoms I usually hunt in. Dried blood and "black land" mud can stay on them for days sometimes.
I know I know. No they are not house dogs but they do get a little house time.
