Got a calf with a lump under her neck right behind her jaw. See no sign of external injury and not sure how long it has been that way. Feels like it has some hard tissue but not lump seems the skin is baggy there more than anything. She is only about a month old , one of my neighbors who has been around cattle all is life thought it might be an old bite and did not think it was infected. She does not act like its painful when I touch it. Mentioned it to our vet and she said give her LA 200 for now and see what it does. Any ideas?
