I have a 2 year old yorkie his name is Hersery, He had his baby canine tooth pulled last week because it was broken off and infected. Now after a week of it being out I noticed that his glands are swollen behind his ears, My question is, what could it be and what can I do for him, it doesn't seem to bother him but he does scratch at them and likes them to be rubbed.  I just spent 200.00 on him and my funds are limited. Please try to help me. Thank You Patricia and Hershery

Almost certainly he has an infection and requires treatment, it should not be more than the cost of the consultation and the drugs.
