Just an update. I haven't noticed any real improvement, unfortunately. The tumor is definitely still there and not shrinking. Levi very much dislikes wearing a bandage on his leg all day. We had to cut all of his hair off his leg...which led me to cut off all of his hair. He just looked too funny with one bald leg and three hairy ones.
Broke my heart, but he's now stylin' a short summer cut. He is in such good spirits.
Looks like we are back at the vet on Friday to make a Plan B. I'm still hoping the steroid will kick in over the next few days. If not, then we'll do what the vet recommends next.
Thanks for all of the well wishes. Levi and I appreciate them so much.
