These are excellent suggestions. Thank you so much for taking the time to answer in such detail! I am going to take these in to my vet tomorrow.
One more quick question: In your opinion -- and I know there's no way to know for sure outside of a guess -- do you think Jack is in a great deal of pain from these lesions? I know with a dog it's often hard to tell.
Thank you so much for your time. Jack and I really appreciate it!
All our best,
Dan and Jack
