Pet's info: Dog | Fox Terrier | Female | spayed | 9 years and 5 months old | 25 lbs
Good day, my 10 year old fox terrier has heart disease and has been on Fortekor and Hills Diet HD for 8 years. Suddenly she has a very severe allergic reaction, which cortisone is not helping for. Can I feed her an alternative dry food to the HD? I don't want it to affect her heart. I only feed her the HD, no other foods. It started 2 months ago, and two rounds of cortisone has no effect. I am scared a third round will damage her kidneys.

If you think that the HD is the cause of the sudden severe allergic reaction, than switching foods might help. However, in my experience, sudden severe allergic reactions don't typically occur from foods. Typically they are from something else in the environment. With regards to food, another good choice for cardiac disease is the Hill's or Purina Kidney Diet. The kidney diets and heart diets have very similar ingredients due to the fact that they are both attempting to control the same things. The good news is that the majority of both dogs and cats absolutely love the way the hill's K/D diet tastes. Hope this makes sense.
