Found a penny sized red lump under dogs jaw. Wasn't there this morning. When should I get it checked out?

Thank you for the pictures. I wouldn't rush Topsy into the emergency clinic, but I would recommend having this evaluated sooner rather than later (next day or two). It is hard to tell from the pictures if it is skin related or more involved. Some possibilities include skin irritation from something that she came in contact with, an insect bite, possibly tooth related, or maybe a foreign body. If she will allow you you can lift her tongue and look around her lips to see if you can see any potential source of irritation. If she will not allow you, or the lump seems to be uncomfortable to her then I wouldn't push her and definitely have her evaluated by a veterinarian. I hope this gives you some direction. I am available for consultations if you have further questions or concerns. Feel better soon Topsy!
