I was just wondering my Jackrussell is 7 and very calm and loving she has really good teeth and no plaque that is out of the norm for a dog.. I was wondering if its normal for bad breath and becasue of the winter months do they tend to want to be relaxed and sleep allot?? she is getting older I just am concerend about the dog breath my min pin does not have that problem and she is the same age... I give them the dental spray for plaque and breath along with dental care you add to water.. is it just the personality of the dog??
