PROBLEM: Arm & Hammer's baking soda is aluminum free, they just don't write it on their packaging.  I wasn't sure so I called them and they said there is no aluminum in it, and they would have to state it if there was because people take the product internally.  This leads me to believe that there just isn't aluminum in baking soda.  And researching it showed me that there might have been in the past, but not anymore and not for a long time.  I resent that Bob's Red Mill writes "Aluminum Free" on their package and then charges a premium for their product.  It's also arsenic free, I hope.  If they label it "Arsenic Free" will we assume other brands aren't?  I don't like that kind of marketing.

SOLUTION: Negative

PROBLEM: Went into the dumpster the very first night. My dog Loves peanut butter, I thought these would be perfect, i was WRONG. These are worse than the dog food they hand out at bank drive thru windows

SOLUTION: Negative

PROBLEM: I got my dog the Paw Flapper because he's a Basset Hound mix and loves to use his nose. He's also pretty smart, so keeping him occupied can be difficult. Unfortunately, this is a super simple puzzle. The first time he played with it, it took him about ten minutes to find all the treats. The next time, it took five minutes. There really isn't anything that challenging about it. Opening the flaps takes my dog a second, and all he has to do is keep pushing his nose into the holes to rotate the top and find all the treats. He had fun, but then it's a toy full of treats, so that's a given.  The puzzle does seem to be well made though, so it's not a bad product. It just isn't challenging enough. I'll be returning it and trying one of the other puzzles.

SOLUTION:
Negative
