[EX Q]: I love VitaMuffins, but my supermarket sells one box of 4 muffins for $6.29.  Instead I bought the mix, 3 boxes for $16.00, and each box makes 12 muffins. Instead of $1.62 per muffin, the mix only requires water & eggs and works out to about 48 cents per muffin, and very easy to make. That's a great deal.
[EX A]: Positive

[EX Q]: Our cocker spaniel is now nearly 10 years old, and the solid gold food I'd been feeding him suddenly changed its formulation over a year ago(with no notice on the packaging), and he became subject to unexplained stomach upsets.  After the contaminated food scare even tho Solid Gold was not recalled, I decided to switch, and this formulation is perfect for him to not gain too much weight.  Newman's own is a brand I totally trust and have bought snacks for my human baby as well for years.  After a year on this food, my dog is doing fine, but I do notice a need to supplement with fish oil for a healthier coat.  That may be age related as well.  But the stomach upsets have stopped.  And I feel better knowing I am not exposing him to additional pesticides and hormones by going mostly organic with this formula.
[EX A]: Positive
