Hi Snowdancer ,
My dogs are big fnas of Northern biscuits with the exception of the type with trout. It was the one treat that did not go over well in my household... of course my guy still ate them-- but didn't gobble them up like other brands.
I haven't noticed PB breath... although I think I am immune-- DH eats PB at least once a day, every day. I think that's one of the reasons Riley & Dakota like PB flavoured cookies :-)
