She is 2 yrs. old and weighs about 47-48 lbs. As for the probiotics, I will go to the feed store and check on that as well...how do I integrate those into her diet? ie, amount, frequency, etc. I wonder why the vet has never said anything about allergies? He just says that she has immune problems and eventually, the yeast infections will cease. They haven't and now this with her feet...its just getting to be too much. Like I said in my earlier post, she sleeps alot now and seems miserable...itchy, scratchy, stinky...LOL
Probiotics at the feed store are not going to help with the yeast, yeast needs a special plan of attack. I agree with it possibly being food allergies and grain related. STOP all treats and take back the rest of the Iams to the pet store even if it is not a whole lot. Tell them your dog developed an allergy and they should refund your money. Start with a good grain free diet I personally like Taste of the wild Salmon because it is grain free and lots of fatty acids to help with coat health. Now when you switch food she can only have kibble no treats at all and it will take several weeks on the food to see if it is food related. It takes time for the the body to reset so don't think it is not working only after a few weeks give it two months on the same food unless she drastically gets worse. If that happens then you need to look what was in that food and try another grain free but that scenario is really unlikely. Next clean her ears out really well and put in the solution in this post.

Use it like it says and stop all other ear meds. You need to kill the yeast but also restore the correct Ph to the ears and that is what is lacking in many meds the doctors give. Next I would also hit is hard with some antibiotics to help clear up the infection from the inside and any secondary bacterial infection that develops from the scratching. Something like clavamox will do.
Next after the course of antibiotics you need to start with probiotics but not just any probiotic you need one that will attack the yeast.
You want to go to the health food store in the refrigerated section and look for acidophilus bifidus and look for the live culture. It is found in like a yogurt shot in the refrigerator.
You want to start the acidophilus bifidus after the antibiotics are finished. Antibiotics strip the gut of all the good and bad bacteria so it would just kill it every time she took her antibiotics so you wait till after you are done. More about acidophilus bifidus and it killing yeast can be found here.

Next for a topical like the feet you can use white vinegar and water like half and half to make a wash for the feet and it kills off the yeast to help out. It does not prevent it from growing but just kills it on contact let it soak for a few min then wash off.
Using an approach that hits it from all angles is the best way to combat a yeast infection that will not go away. I have treated many dogs with yeast infections like this but I learned it when I was battling yeast myself.
I got a yeast infection in my breasts when I was breast feeding my son and everything I tried did not work. It was the most horrible painful thing in the word and I battled it for 2 months. Nothing worked, no meds the doctor gave me, not the vaginal yeast cream.... nothing! So I did a lot of research on yeast and found out what kills it and how to treat it from several angles. Yeast also feeds on sugars and if you look at some food they are high in sugar content and that is something we do not really look at when selecting dog food but it is important when you are battling yeast.
I hope this helps and give a better picture of how you need to combat this. If you cannot get a prescription for clavamox from your vet you can use Cephalexin that you can get over the counter and I can help you with that but ask for clavamox first.
