Ok, it has been awhile since I have fed strictly dry food, let alone dry food to only 2 dogs each just under or right around 40lbs. The one is a moderately active 3-4 yrs old Shepherd mix the other is a pit or terrier mix of some sort around 6 months with a slightly higher energy level. Taste of the wild High Pairie was being fed but owner changed back to Iams Naturals because a 5 lb bag no longer lasted her 2 weeks it only lasts 4 days... does anyone have dogs that are similar in age/energy levels that feed TOTW?? If so how much do you feed and how much do you pay a month for food. Because, I'm trying to rationalize the change. I should mention the inital change (done long before puppy was brought home) from Iams to TOTW was because of ongoing health reasons the older dog has (very sensitive system/problems with acid reflux) and she was unable to gain/maintain much needed weight on IAMS.
