I'm taking a shot here to see if anyone has ever heard of VIVA biscuits?

I recently picked up a small box for my German Shepherd and she loves them.

Ingredients: Soy flour, pure cane sugar, glucosamine sulfate, soybean oil, chodroitin sulfate, carrot, spirulina (algae), apple juice(dehydrated), carrot juice (dehydrated), banana juice (dehydrated), salt, magnesium stearate, natural & artificial flavours, hydrolyzed soy protein, caramel, niacinamide, calcium pantothenate, pyridoxine, riboflavin, vitamin B, ferrous sulfate, zinc sulfate

Each serving to contain:

Glucosamine 400 mg
Chodrointin 200 mg
Carrot 150 mg
Spirulina 150 mg
Apple 100 mg
Carrot 100 mg
Banana 50 mg

crude protein 26%
fat min 5%
fiber max 3%
fiber man 10%

How does this sound to you? I couldn't find any reviews of their products on-line.

With the second ingredient being sugar, I'm sure dogs go for them.

Honestly, while it's not totally atrocious (like begging strips and the like etc.) it's not something I'd personally use. There are very nice glucosamine/chondroitin treats that aren't full of soy and sugar.
