I've fed Iams to all my dogs, and for the past year or so I have really been trying to swich but my mom swears her dogs growing up lived long healthy lives and thrived on crap like hy-vee brand dog food, and won't swich for more than one transition bag and one whole bag. I had him on Bil-Jac for about a month because he loves it and the liver treats, and he was on the chicken liver formula and did great but had several small seisures over that time and my mom switched him back to Iams because 1. she thought the food had something to do with the frequency of his seizures 2. it was like $20 a bag (Niņo refuses to eat the food if it has been out of the bag for more than a week or 2 so we have to buy 7 or 8 lb bags) but this bag was like $20 lbs or something! 3. (and the main reason) We can only buy it at Petsmart. I have offered to pay the difference for any more expensive food, but she doesn't want to go to petsmart that often (even though we go for crickets anyway! ) When I get my drivers license I will probably swich him to something, I really don't know what.
My stepdad is convinced that by products are ok, that they mostly include stuff healthy for dogs but not people.
