I saw an ad on tv for a new treat for dogs that I thought you may be interested in. It's called Pedigree Joint Care Treats by the Pedigree Pet company. It's for older dogs and dogs with joint problems. It's supposed to be full of good stuff to help keep their joints healthy. I think it's new so may not be available in Canada yet but maybe they would have some information on the web site:
www.pedigree.com
Just wanted you to know. Your vet may have it.
