My dog Knuckles, near his neck has swollen on his left side. The swollen part is firm to the touch. He is still able to breathe normally and drink normally, but his appetite isn't how it normally is.

HI, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Knuckles! I would make an appointment for Knuckles to see his Vet. The swelling can be from an infected or inflamed salivary gland or lymph node. He could also have an abscess from foreign material penetrating the mouth or from the outside, be experiencing an allergic reaction or possibly even have a tooth root abscess. An enlarged lymph node can also be from lymphoma, a type of cancer. Usually though more than one lymph node is swollen if a dog has lymphoma. I hope this helps and I wish Knuckles a speedy recovery!
