I get daily pet newsletters and just got one today on the dangers of giving regular meds and food to dogs that contain xylitol which is a sugar that is in alot of meds and prescription drugs and in alot of things you might not even realize it is in. It is very toxic to your dog. Here is a link you can go to, hopefully you can just click on it, but if not, you can copy and paste it. It is a short but interesting read.
