Hello All,
My first post here.
I registered two nights ago, but only just today was activated.
I have a vet appointment tomorrow, but tried to do any and all research to understand as much as possible ...as an informed parent

I am going to ask everyone's opinion anyway and will keep you posted on tomorrows diagnosis.
A week and a half ago we noticed our heeler limping very lightly and did not give it too much worry as she is very energetic and plays rough, I inspected her as usual and found what I thought was a scrapped pad - no big deal.
last weekend she was not improving so I inspected more thoughly and found a small cottage cheese kernal size growth between two toes. It looks as though it is filled with puss(infected) and would pop easily, but it did not during here normal activities. It hurts her for us to touch it, but what is interesting is she still attacks all balls and tires as usual, runs & plays.
I have attached a photo for reference.
This is a great forum, thank you for any comments.
