My puppy has a lump on the right side of her face. My dog sitter pointed it out to me when I picked her up from daycare today. It is soft and tender to the touch. She does not like when I try and touch it and I am unable to look inside of her mouth. It seems like it is really bothering her. She is eating and drinking normally this evening, but created herself and seems like she is in pain. I made her a vet appointment for tomorrow afternoon but is this something I should be seeking more immediate attention for?
