My dog loves Greenies Dental Chews.  If you have a dog and have not tried Greenis Dental Chews, you should.  Your dog will love them and they are good for your dog.  They also have them for cats, but I can’t provide any opinions on the cat version.  The only thing I know about cats is my dog likes to chase them!!  The Greenies Dental chews are 96% digestible, and come in 5 different sizes.  Each size is different in texture and is made to suit a specific size dog, so its very important that you pick the right size.  The Greenies  also have added vitamins and minerals, proven to remove plaque and tarter, giving your dog fresh breath and reducing gingivitis.  I actually take my dog to get her teeth done once a year, but  I know a lot of owners do not, so this is a good alternative that your dog will love.  Greenies was the first to receive seal of approval from the Veterinary Oral Health Council® for tarter and plaque removal.  Studies have shown 62% reduction in tartar, 77% reduction in teeth stain formation, 14% decrease in plaque, and 31% reduction in bad doggy breath.  Not sure how they tested the bad breath result??  You can currently get a deal on Greenies at petsmart.  Find the greenies coupon and additional petsmart coupons at savingsheadquarters.
