Gal next door and I went in on piglets together. One started getting a growth on the side of its neck 2 weeks ago. It is still eating running playing. Hard roundish growths. The growth has hair on it. Vet thought it was tooth was lanced given antibiotics. It is still growing it is as huge now and nothing came out of lanced area. Have noticed another growth 2 days ago on front of front leg this one has lost hair and is black. Shots? Yes Breed? Chester mixes Can get picture out tonight after she gets off work if this would help.
