I just saw a show on tv about dangerous things to give your dogs. Of course the "greenies" were on there, but also they said anything that does not dissolve rather quickly in water could be very harmful to our little ones. I was giving mine those hard "bimple" bones almost every night. I will definately NOT be giving them those anymore. They also talked about the toys that have "strings" hanging from them being very bad. I had a couple of those too
, and tossed them in the trash as soon as I heard this.
