Query: Dog Vitamins

I used to buy these vitamins at Wal-Mart and for years my dogs had them everyday and they enjoyed them. Like so many products from W/M their buyers decide to buy some cheaper or imported brands, and the new ones that W/M brought in are terrible.My dogs would not even nibble at the new vitamins, in fact when I put them into their food they would not eat their food because they are so bad.It took awhile for me to find these, so glad Amazon had them.Bottom line my dogs love these, they are 8,7 & 5 years old and they have always been healthy little guys and still act like puppies and all I can say is they (Hartz Dog Vitamins) sure work for us.
