Skinner had so many things going on that we did a needle sample from the growth in his arm pit, and a whole bunch of blood tests. Vet said she wasn't worried about the very odd nipple stuff and thought it was most likely really skin tags. Digestive issues and big anxiety likely just the travel and fireworks and disruption. All the tests are perfect. We are going to add bone broth to his food to encourage his eating and ignore the lumps and bumps unless they interfere with movement. IOW, he is an old man with fatty bumps, skin tags, a sensitive belly, and farts a lot. At 8 years old! Anyway, phew! We were really worried.
