I was just playing with Chloe, and as she was settling down to lay in my
lap, I noticed a few things.

1. sores under her arms - she had this a couple months ago, the vet gave me
a spray, so I have started spraying it again.

2. she's been chewing her feet alot lately - and I looked and between the
first and 2nd toe on the front left paw is pretty red.

3. down just above her ulva is a red raised dot - I think it might be a
fire ant bite (as it looks similar to how we humans react to those bites).

4. then I looked and on one of her elbows I noticed a few dry scaley
patches. I know I've seen dogs in the past with really bad scaley spots on
their elbows.

What is it? And what can I do to keep it from getting any worse?
