Please call your vet in the a.m. and explain to them the situation to see if they can squeeze you in any earlier. It’s always best to get any lump or bump diagnosed. If they can’t, I personally would make an appt. with another vet. Could be nothing, but it could be something that needs immediate treatment. For the couple of days or so before the appointment I would suggest you not give your dogs antihistamines as they may mask the situation.
