I swear this dog is gonna give me a heart attack before I turn 35! I woke up this morning and noticed this big DARK red spot going around the sore we have been trying to heal. Anyone know what this red blotch is?? I called her vet already and left a message but I'm nervous on what it is. Is this what hives look like?? I checked her over and see no other spots just this one and it's going up to her neck area.
