I have a labrador dog that has a lump under
. It just randomly appeared after being sick, i'm guessing that still considers him sick. He is 6-7 months old and he has never received any shots. While breathing he makes a semi-loud wheezy noise, and when he swallows it looks like it bothers him every 5 swallows or so. At first i thought it was just dangling skin, but no, this is a ball type thing, not major, but it feels kind of like theres liquid inside of there.
