Hi what is the best dog food to feed a doxie I am currently feeding natures recipie with fruit and vegetables thinking of switching to eukanuba food for doxies would it be better to stick with the natures recepie and give a vitamin supplement for the doxies joints and vertabrae one doxie has a bad back thanks for the help

I doubt it makes that much difference. Although different chows contain different ingredients, they are all formulated to have about the same nutrients, just getting them from different sources. Much of the difference are just marketing hype. If they are doing Ok on what you are feeding now, I would stick with it with no supplements.

One of the most important thing is keeping them lean. Their backs can't take the extra strain of excess weight. Evaluate them using LongLiveYourDog.com - Life Span Study - Rate Your Dog adjust how much they are eating to bring them into their ideal body condition.
