ok time for the commercial
If they have it in your area try Propet- an alternative to the name brands. Propet is owned (the last time I checked) by Carnation Inc. It's about $0.50 per pound or $25 per 50 lb bag. Out of 3 dogs so far:
1. All have gobbled it down first time, every time. My female does better than a vacumn.
2. No food allergies or skin problems.
3. No apparent nutritional deficiencies.
I have to just about wear sunglasses my little black male part Lab shines so. ;)
The only problem I've run into is that the performance is rich enough, that once the dog gets to about 4-5 yrs you have to switch them to the maintenance forumula else you get fat puppy.
P.S. Trash the Ole Roy.
P.S.P.S. Grass is interesting. My previous dog, and my current male if they ate/eat a little grass, the result is the usual. My female must be part cow. She can eat it without any ill effects.
