With your help, I switched Ernie to Eagle Brand Holistic senior food. It's been a great transition and I didn't think he could eat food faster but he does with his new change. I mix a little sweet potatoe once in awhile and it seems to slow his eating a bit.

My question- His poo is much softer and greenish versus the brown from his old food. Sorry, Not that I think you're an expert on poo   He's had anal gland problems in the past, I though a little  firmer was better.

 I was thinking I would see better coat changes with this food. His coat is dry. I'm going to start with the fish oils.

Has it been soft and green the whole time he's been eating it?  The soft poop can be from over feeding, but the green?

Hmmmm.  That's 368 calories.  Technically that's enough for a 22 pound dog.  How long has he been eating it?  I guess it's possible that it's just not for him.  I forget how old he is.  Maybe he needs more fat in his diet, have you tried another EP product?  I recently tried their new food for small and mini breed adults.  It's main ingredient is fish so it's a nice switch for my two guys.  I wish I knew what to tell you. 

Ernie's 9 y.o.     Switched his food to Eagle in February
He has gained weight with this food, although winter and less walking.
Haven't looked at the other Eagle Pack varieties because he's a senior. Should I give the small/mini a try before switching?

I really don't know.  If you did you'd have to cut way back,  it has 424 cals per cup vs 368 in the Senior..  How much does Ernie weigh?  I think I'd try cutting back to 3/4 cup of Senior food and add omega 3 fish oil and see if that helps.
