Andrew Ray, so sorry about your goat. My mums goat is in the same boat as your late goat. My mums goat has his chain stuck underneath a thin layer of skin on the top of his neck. He has a hard thingy that looks like a mass but I don’t really know what you would call it. I’m so scared for him because this is the first time it has happened. I found out from my mum that it’s caused by him pulling on the chain and yanking on it. I feel so heartbroken right now because I’m not an expert or known much about goats except for them needing their coats groomed, fresh water and lots of food (grass). Once the vet looks at him hopefully tomorrow, I will make sure to build a fence around his area around the backyard to ensure he never gets chained up.
