Q: My dogs LOVE duck treats and have been getting the chicken happy hips for years so I though I'd give the duck a try.  Bad idea.  The treat was too tough and stringy for my small female Westie to pull apart and she ended up choking and vomiting.  I order by subscription and had to make cuts in the strips with a poultry shear to use up the 6 bags.  I too hate the fact that these are made in China, but my little guys need extra condroitin and glucosamine so I'm back to the chicken formula.

A: Negative

Q: I had a handful of these crackers last night - and though they are tasty, my hands, face, and ankles swelled to a ridiculous size.  I wasn't sure if it was the crackers or something else I ate - so I ate them by themselves at lunch - and again, I am a swollen mess.  I didn't realize the MSG content was so high.  I won't be eating these again.  If you react to salt, sodium, or MSG - just stay away from these tasty little buggers.

A: Negative

Q: I have a slightly different version of this - different brand.  My son started using it around six months, and he really enjoys it.  He DOES get messy if he eats something sticky or juicy like banana or watermelon, but whatever...  Anyway, I also had trouble cleaning it, until I tried scrubbing it with a nail or vegetable brush.  That works pretty well.  It takes some time, but not as much as it would take to run food through a food mill or blender, or cut it up, then clean it up off him, the chair, the floor, the dog, me, well you get the picture.

A:
Positive
