While petting my dog today I felt bumps on the back of his neck and in between his shoulders. I looked closely and found them to be scabs but i haven't seen him scratch himself that much. Any suggestions as to what it can be . I know it's probably dry skin due to the weather change but anything else would be helpfull. Thanks! also what can i do to make it less painful for him.
[EDIT]: after looking even more closely I think its more serous theres like holes in his skin im freaking out im taking him to the vets tomarrow asap
