My 13 year old Sheltie had oral surgery about a month ago.

He had approx 5 teeth removed with laser. Recently he will not let you touch the outside bottom of his jaw. I was able to get a finger in his mouth to feel around and I felt a sharp either bone or tooth. Could this have been missed during his oral surgery and causing him the discomfort?

I’ve also had to change his dog food due to allergies; scratching biting paws and tail, dry scaly skin. He was on Pro Plan Bright Mind Adult 7+ Chicken for about 8 months. Did show great mental response to it, but still had allergy issues. Recently started him on Blue Basics Grain-free Salmon & Potato mixed with couple teaspoons canned same formula & Licks anti-inflammatory. Seems to be doing well with it as far as allergy issues. Had couple loose stools. Think might be due to canned food. He was very restless last night and I think it’s due to the mouth issue. Hope all this info helps you with you expertise advise. Thank you.
