I use a vet shampoo Malsorb I think it is called to help control yeast infection and for sensitive skin .. no perfumes, etc. My ShihTzu gets yeast odor very easily when not on this shampoo. Also has had the red you talk about and it was a moist yeast infection in my dog's case in the area you describe and cream for a week cleared it up ok. Then she ended up with that in her ears recently and liquid of the same med worked fine.

Do you mean Human Pantene or is there one for dogs? Just curious....Karla
My dog has a little reddness under his arm pits and just a little one on his chest, but for my dog it comes and goes. My vet gave me some time of lotion i place it on him it seems to help him. Maybe you should ask you vet about the lotion, im sorry i dont know the name of it. I hope this helps, i am not usually on this forum. But I love dogs
