My Saint's coat is shiny and definitely feels softer since he's been eating Solid Gold.. He's eating the Hundenflocken (lamb) now.
It is harder to see the shine on a light colored dog.. But when Bubba is outside the shine is more noticeable.
Here's Bubba's before and after pics. In the before pic He was eating Science Diet large breed puppy (which the breeder was feeding) and the after pic was just 2 weeks on Solid Gold Wolfcub.
Before (his ears were soft and shiny, but his coat was dull)
After (Shiny everywhere.. lol)
And Bubba now eating Solid Gold Hundenflocken. He's still nice and shiny but harder to compare since he's lost his puppy coat.
I hope these pics are not too big.
Just thought I'd post a comparision on a light colored doggy.
