My dog has a potassium allergy. Should I avoid all potassium in food?

First of all this information regarding peas, potatoes and lentils is not true whatsoever. you can feed him any brand of food that is grain free and chicken free, many companies have at least one product that will fit this description- Orijen for example have a food called "six fish", it's grain free and there is no chicken in it either.

Dogs with food allergies are difficult because of the balance between the best nutrition and the type of protein used in these food. The most ideal food would be a prescription kidney diet (i.e. science diet k/d) but most of these have chicken in them you could look at Purina NF the dry kibble as there isn't any chicken listed on the ingredients. I would call Purina or have your vet call and confirm that they don't have any chicken in the dry kibble. If you choose this food, your vet will likely have to order it for you and give you a written prescription for you to buy it. I would not put him on high protein diets like blue buffalo or wilderness. These diets put a lot of strain on the kidneys. I would look into Natural Balance venice and sweet potato. If he is really allergic then I would talk to your vet about whether he should be on a prescription hypoallergenic diet. I hope this helps!

Electrolyte abnormalities are a known side affect of heart medications. It's important to make sure she's eating a good-quality balanced dog food so that's she taking in the proper electrolytes. It is also wise to periodically check her blood work to test the electrolyte levels and see where she is. If there are some that are either high or low, your veterinarian may recommend supplementation. There are also heart diets on the market that may be beneficial to her. Hill's and Royal Canin both make cardiac prescription diets. Here are a couple of links for additional information about what you can feed her. I hope this helps! http://vet.tufts.edu/heartsmart/diet/ http://www.vermontveterinarycardiology.com/index.php/for-clients/feeding-the-cardiac-patient

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.

Your dog should be eating dog food regularly. Homemade diets rarely have the correct amount of nutrients that our pets need and this can lead to medical problems in the long run. I would recommend trying to find a diet that is made from pork. There are several companies that specialize in making limited ingredient diets. You can also try other novel proteins like rabbit, venison, or kangaroo based dog foods.

Feeding her just eggs would not be a balanced diet for your dog. If you think she has a food allergy then you would need to feed her a novel protein (venison, duck, kangaroo, and rabbit are examples of novel protein sources or a hydrolyzed protein) You could use prescription diet z/d or d/d. You would need to feed the only diet for 6-8 weeks and monitor for improvement.

Thanks for using Petco Pet Education Center, formerly Petcoach! Fortunately, there is an option for Bizu that is a newer poduct from Royal Canin, which is a multifunction pet food. They have a combination diet that is urinary (like he is on) and hydrolyzed protein, which is specifically for allergies. Hydrolyzed diets may use chicken and other proteins in them, but the protein sources are broken down so small that the body doesn't recognize them and they don't cause the itchiness we see with food allergies. This may be a great option for him!
